What is the JavaScript React Developer role?

JavaScript React developers, also known as front-end developers, are in charge of creating dynamic websites using a programming language. They take care of the front-end part, i.e. the visual side of the site, unlike the back-end developer. To find out more, you can read this article on developer jobs.

 

A front-end developer’s missions typically entails:

  • Understanding the project they’re working on to develop the most satisfying features and interfaces for their client.
  • Implementing mockups with a keen eye for detail and rigorous standards.
  • Using best practices to structure HTML, CSS and Javascript code.
  • Using frameworks such as React to build powerful and modular applications.
  • Using tests to monitor their applications and ensure the highest quality service.
  • Providing technical and functional documentation of the site for their clients and colleagues.
  • Optimizing page load time.

Why take this program?

This program was created by our instructional design team. Our pedagogical method is based on the realization of real-world projects and one-on-one, weekly sessions with a professional web development expert as your mentor.

The idea is simple: to learn effectively, it is important to be active in your learning. Within this path, this involves completing projects based on scenarios from the professional world. Your mission: look for solutions, create your deliverables and present them convincingly in front of your mentor!
