What Do JavaScript Developers Do?

JavaScript has been the backbone of web development since its creation in 1995, gaining significant usage over the years. Today, it is the most popular programming language, used by over 98,8% of websites.

If you set your mind on building a web application using JavaScript, you must go through the hiring process first. However, you won’t succeed in finding good JavaScript programmers for hire without learning what they actually do. Let’s find out the primary responsibilities of professional JavaScript developers and their skill sets.


JavaScript Developer Responsibilities

JavaScript developers are responsible for creating interactive front end and ensuring high performance on web, desktop, and mobile. JavaScript engineers can build and execute tests for units, services, components, etc. They can also access external APIs and data sources to gain information about third-party services.

hire javascript developers responsibilities

In a nutshell, JavaScript developers have the following responsibilities:

  • Develop and maintain web applications.
  • Write clean, reusable code.
  • Collaborate with front-end and back-end developers to integrate user-facing elements with server-side logic.
  • Ensure the technical feasibility of UI/UX designs.
  • Optimize applications.
  • Troubleshoot and debug applications to resolve issues.
  • Implement responsive design for seamless user experiences across devices.
  • Conduct code reviews.
  • Work with APIs and data sources.
  • Write unit and integration tests.

Notably, about 45.5% of JavaScript developers also use TypeScript in their work in some way. In fact, TypeScript programmers can perform all the tasks that JavaScript specialists do. The main difference is that JavaScript is better suited for rapid prototyping and dynamic features. In turn, you can hire TypeScript developers for more complex projects with long-term maintenance.

hire javascript developers vs typescript

When looking to hire JavaScript developers, preselect people with the following list of technical competencies:

  • Degree in Computer Science, Computer Engineering, or a related field;
  • Previous experience with JavaScript and ES6+;
  • Proficiency in CSS, HTML, and JavaScript frameworks and libraries;
  • Experience with databases like MySQL, MongoDB, SQLite, etc.;
  • Ability to create custom modules and components.

You can use this list to hire TypeScript developers as well. However, also pay attention to their experience with TypeScript-specific features. Make sure candidates know the TypeScript type system. In particular, test their ability to create and manage custom types, interfaces, and generics. Also, check their experience in integrating TypeScript with existing JavaScript projects.


JavaScript Developer Tech Skills

Before we check specific platforms and other techniques to help you hire JavaScript developers, let’s look at the required technical skills.

First of all, hire JavaScript experts with proven experience in this programming language and ES6+. They must know JavaScript basics, like functions, variables, data types, objects, control structures, and prototypes.

On top of that, find developers who have in-depth knowledge of JavaScript libraries and frameworks. Whether you’re looking for front-end or back-end expertise, you may choose some of these technologies to focus on:



React is a popular library for building user interfaces, particularly single-page applications. Developed by Facebook, React allows developers to create reusable UI components and manage the app state. Its virtual DOM feature cuts direct manipulations of the actual DOM, so React apps have high performance.


Vue.js is used to build UIs and single-page applications. Vue is easy to integrate with other projects and libraries. It features a reactive data binding system and a component-based architecture.


Angular is a frontend framework for single-page client applications using HTML and TypeScript. Developed by Google, Angular provides tools for building large-scale applications. It includes two-way data binding, dependency injection, and an extensive suite of developer tools.


Node.js is a runtime environment that allows developers to execute JavaScript code on the server side. Node.js is ideal for scalable network applications, as it uses an event-driven, non-blocking I/O model. It's widely used for creating back-end services and APIs.


Express.js is a minimal Node.js web application framework that provides features for web and mobile apps. It is often used to build single-page, multi-page, and hybrid web applications. Express simplifies routing, middleware integration, and server-side logic.


jQuery is a fast, small, and feature-rich JavaScript library. It simplifies HTML document traversal and manipulation, event handling, and animation. jQuery is still widely used in legacy codebases and simpler projects.


Ember.js is a framework for creating web applications. It includes a router, a component-based architecture, and a service layer for managing the app state. Ember's convention-over-configuration philosophy helps developers build scalable applications with less boilerplate code.


Backbone.js provides the minimal structure needed for web applications. It offers models with key-value binding and custom events. Backbone.js is a good choice for projects where developers must maintain control over the framework's behavior.


Meteor is a full-stack platform for building web and mobile applications in pure JavaScript. It includes a server-side framework, a client-side framework, and a database solution. Meteor's real-time data synchronization feature makes it ideal for building real-time applications.


Polymer is a library that uses web components to build reusable custom elements. Developed by Google, Polymer simplifies creating encapsulated and interoperable components.

Since this ecosystem is constantly being updated and extended, a JavaScript developer would be familiar with the new versions.

Next, hire JavaScript developers who know Document Object Model (DOM) manipulation. This expertise allows coders to interact with HTML elements, modify their properties, and update user interfaces.

It is recommended to hire JavaScript programmers who are familiar with databases like MySQL, PostgreSQL, MongoDB, and SQLite. It will help your team handle data storage and retrieval efficiently.

Below is a table of JavaScript developer tech skills that you should test:

Skill Category

Front-end development

React, Vue.js, Angular, Preact, Ember, Svelte, Alpine.js, Lit, Solid, Qwik, Stencil

Backend development

Node.js, Express.js, Nest.js, Fastify, Strapi, Koa.js, Hapi, Meteor

Rendering frameworks

Next.js, Nuxt, Gatsby, Remix, Astro, Eleventy, SvelteKit, Docusaurus

Cloud services

AWS, GCP, Azure


Docker, Kubernetes

Besides technical skills, every developer must possess a certain set of soft skills to ensure smooth collaboration. Hire JavaScript developers who have an eye for detail and can quickly detect possible mistakes. Errors slow down the development process and lead to higher costs.

Also, look for a wordsmith with good communication skills who can convey their message to others and ensure everyone is on the same page. Finally, dedicated programmers are team workers and can cooperate with others, give or receive assignments, and contribute to the project.

5 Options to Find JavaScript Developers

Much like any other hiring process, recruiting a JavaScript developer is a challenging task. There is still a scarcity of professional software developers in contrast to a much higher demand.

On top of that, software developers are expensive and ask for an inflated paycheck, together with benefits and incentives. Besides that, hiring managers and recruiters often lack the basic technical education to evaluate a candidate’s knowledge and expertise. Finally, the hiring process is quite long and costly.

To overcome these issues, let’s find out the best options to hire a JavaScript programmer with its pros and cons.


JavaScript Community

Given the willingness of the IT world to share knowledge and know-how, there are many online communities for software developers. Although they mostly exist for developers, hiring managers also have access to such websites and can look for candidates.

StackOverflow is one of the most famous online IT communities where users can share their knowledge, ask questions, and contact each other directly. Being a community with almost 23 million users, it opens a large talent pool for many businesses. Since it rewards helpful answers and suspends untactful behavior, users can be sure to find some of the best answers here.

GitHub is another popular online community for software developers to exchange knowledge and share their code. It is less focused on direct communication and more on seeking collaboration and sharing the latest trends.

All in all, online communities are a good place to hire JavaScript developers. On the other hand, you will have to contact and evaluate the candidates yourself, which is a lengthy and costly process.


JavaScript-Related Tech Events

There are numerous tech events that take place around the globe. People in the IT industry get together to discuss the latest trends and exchange knowledge. More and more conferences are going online, which makes them more accessible for everyone. When you participate in such events, you expand your professional circle, increase your knowledge base, and potentially meet the right people to hire JavaScript developers.

JSConf is a conference that invites many speakers to converse and share their expertise about JavaScript and its ecosystem.

React Summit is another annual in-person and remote first JavaScript-related conference that brings developers together to discuss the latest trends in this technology.

Unfortunately, even though some tech events are held online, a big portion of them are still hosted offline, which makes it difficult to take part in them. And the virtual events are not very conducive to communication and exchange among the participants.


Freelance Platforms

You can also hire developers online using modern hiring platforms. There are a myriad of marketplaces where you can find potential employees. We will focus on the primary ones, such as Toptal, Upwork, and Freelancer.

Toptal is known for its rigorous vetting process and serves as the ultimate online tool to hire JavaScript developers. Only 3% of all applicants become a part of their talent pool. Although the harsh screening process demonstrates their portfolio’s excellence, it also drives up the costs. Toptal might be a good choice if you need an exceptional mind to generate new ideas, not a typical middle or senior developer.

Upwork is more inclusive than Toptal and does little to zero vetting. It has an algorithm that only checks whether the profile is complete and relevant. This means that you will have to do the vetting yourself.

Freelancer does not do any screening and lets anyone in. It is a good platform to hire remote JavaScript developers who are just starting their careers, but it is unsuitable for middle or senior-level developers.

Toptal and Upwork are the go-to solutions to hire freelance JavaScript developers. If you would like to learn more about these services, their vetting processes, and pricing, look at the Toptal vs Upwork article.



With 1 billion users worldwide, LinkedIn is the biggest business platform that also offers a job marketplace. Candidates can choose location, type of employment, experience, and other aspects to narrow down their search.

Businesses can post their job ads on LinkedIn, thus reaching out to millions and millions of potential workers. The size of LinkedIn has its downsides: imagine how many companies publish their vacancies on this massive platform. Your posting may get lost within just an hour or two.

Another drawback is that it’s a confusing pricing model, where you pay for the number of views, not per job posting. As a result, you never know how much you will end up paying for a single job ad.


IT Staff Augmentation

IT staff augmentation is a relatively new approach to recruitment. DOIT Software is a company that specializes in this method and allows you to hire a development team. The main idea is that a company can “borrow” a worker from software development companies instead of hiring in-house.

hire javascript developers with staffing benefits

You are not required to conduct interviews and tests since the company will do that for you. You only need to provide a set of requirements for the project, and staffing experts will find developers that fit that profile. This way, you augment your JavaScript team with one or several essential workers who will work for you for the duration of the project or task.

How Much Does It Cost to Hire a JavaScript Developer?

The cost of hiring always depends on the type of employment and the worker’s location. If you hire JavaScript developers to work in-house, you will also pay taxes, office equipment, and so on.

JavaScript developer salary


$74,737 - $172,648


$48,223 - $85,025


$45,875 - $78,634

$57,133 - $65,563

Eastern Europe

$19,143 - $49,991

Latin America

$17,689 - $50,498

If you hire a dedicated JavaScript developer to work remotely, you will save much of your budget. In the staff augmentation model, the rates also depend on the developer’s region:

  • In the United States, JavaScript coders earn around $9,500 per month;
  • In the United Kingdom, you can hire JavaScript developers for $7,100 per month;
  • In Australia, rates are a little lower – $6,500 per month;

Say no to a checklist

Instead of going through each point of the checklist one by one, prepare an approximate outline of the interview and try to have a conversation with the candidate.

Come prepared

Not having a checklist does not mean not preparing at all. You must know what questions you will ask and what topics to address.

Train others

Give training on how to conduct an interview with other workers who will participate.

Stay on topic

During the interview, the candidate might go on tangents and talk about irrelevant things, so you have to ensure you are staying on topic.

Now let’s get more technical and go through a list of questions you could ask during technical interviews with candidates of different levels:


If you want to hire JavaScript developers for a junior position:

1. Can you explain what variables are and how to declare them in JavaScript?

2. What is the difference between let, const, and var?

3. What is a Javascript callback function? Give an example.
