- 9. How Much Does It Cost to Hire JS Developers?
Not by chance, JS is in the first position:
- Flexibility. Created products are reusable and not platform-specific.
- Rich interface. New functions are permanently developed for JS; many libraries and APIs exist.
- Versatility. Works well with other programming languages. Supports all operating systems, browsers, and mobile devices.
2. Copying Individuality—This point follows from the first. Because of client-side code execution, there is a risk of your site being copied by competitors. As a result, you risk losing your identity. This disadvantage is especially relevant for an environment such as e-commerce.
- Adding interactivity and dynamic content. For example, show or hide additional information at the click of a button, play audio and video on a web page, display animations, etc.
- Creating web and mobile apps: such as Netflix and Uber
- Creating games that work inside the browser, both 2D and 3D
- Creating stable web servers and server applications using Node.js
Have you already started the project, or are you starting from scratch?
If you’ve already started a project, it’s easier to figure out what you’re looking for. You’ve already decided what technologies and frameworks you need, so you just need to find the best developer with those skills. Then, you can easily list the requirements and determine who is the best fit for your project.
Front-end JS developer—is a specialist responsible for data processing into a graphic user interface. He creates what a user sees in the browser and interacts with.
Back-end JS developer—a specialist who takes care of the server part of the project. In addition, he creates components and functions that are available for a user through the interface.
Full-stack JS developer—is a broad specialist who can create application architecture and its user interface.
Whether you want a site with static content, a basic contact form, or a fully interactive user interface, you can rely on a front-end developer.
Here are some responsibilities of frontend JS developers:
- Development of front-end project from scratch;
- Design of user interfaces;
- Cross-browser and adaptive HTML5/CSS3 layout;
- Collaboration with back-end developers while creating RESTful API.
Back-end developers are responsible for databases and APIs. Their focus is not on presentation but on functions on the server. Don’t expect them to draw or design; that’s not their job. However, suppose you already have a front-end developer who has done the custom part of the project. In that case, the back-end developer will connect the data to the front-end.
Responsibilities of back-end JS developers:
- Development of business logic and back and system for product support;
- Work with databases with the help of DBMS;
- Integration with external services;
- Testing and debugging of application components.
When to choose a full-stack developer?
Responsibilities of full-stack JS developers: Mix of back-end and full-stack duties.

We mapped out the libraries to the potential objectives of your project:
The table lists only the most frequent use cases and examples of the libraries. Your case might be different. Visit Github to familiarize yourself with the list of additional libraries.
The job description should consist of six main sections:
General information about the company: Explain what your company does, its purpose, and its goals.
