How to Become a JavaScript Developer

If you want to work in software development and become a web developer, then you may wonder if it’s a good idea to learn JavaScript. JavaScript is the most popular programming language in the world. It’s also a beginner-friendly language that already comes installed on every modern web browser, so you don’t need to set up anything.

Want to become a JavaScript developer? From the education level and certifications to skills, responsibilities, and hourly rates, we discuss it all so you can make the best decision for your future.

What does a JavaScript developer do?

JavaScript developers are technical professionals who use the JavaScript programming language to develop and implement websites while connecting with the services running on the back end. They may find themselves juggling different programming duties depending on the project requirements.

The main focus of JavaScript developers, however, is usually the user experience and interface of web pages, creating modern and interactive layouts from designs along with other front-end developers, and ensuring the technical feasibility of UI/UX designs.

What skills do I need to become a Javascript Developer?

The following qualities and skills are needed to excel in this career:

  • Strong knowledge and experience with web apps and programming languages, such as Java, HTML, Python, CSS, JavaScript, APIs, as well as JavaScript frameworks, such as jQuery
  • Knowledge and experience in JavaScript libraries and frameworks, like Angular 7+, React, and VUE
  • Experience in software development projects and coordinating with a different development team
  • Experience building cross-browser user interfaces and client-side implementation of RESTful API
  • Basic knowledge of usability, user experience (UX) design, modern web development standards, and search engine optimization (SEO) best practices
  • Experience with back-end development using Node.js
  • Familiarity with code versioning tools, such as GitHub
  • Familiarity with Agile methodologies
  • Understanding of fundamental design principles behind a scalable application
  • Keeping skills sharp with continual learning
  • An inquisitive mind and demonstrable examples of implementing proactive solutions
  • Excellent communication and interpersonal skills, including when working with remote team members and with clients

What are the core JavaScript developer job responsibilities?

JavaScript development is one of the major IT job profiles that professionals can explore. Key responsibilities of a JavaScript developer include:

Some of the main Magento developer job responsibilities are:

  • Optimize components for maximum performance across a vast array of web-capable devices and browsers
  • Manage the software development lifecycle, and fix issues like syntax and logical errors
  • Develop and direct software system validation and testing methods
  • Work closely with stakeholders, clients, and cross-functional departments to communicate project status and proposals
  • Continuously monitor application reliability, debug JavaScript code and web applications, and optimize performance
  • Build software applications following coding standards, as well as build appropriate unit tests, integration tests, and deployment scripts
  • Deploy projects and support dev-ops process to deploy projects in different environments
  • Create database schemas that represent and support business processes

Should I get a JavaScript developer degree or certification?

Many employers prefer prospective JavaScript developers to have a bachelor's degree in a technical field. But there are job listings that do not require a degree, and some positions just a certification from an online course or bootcamp.

That being said, JavaScript developers can benefit from several types of education or certifications to help position themselves more prominently on Upwork:

  • A bachelor's or master's degree in computer science, web development, computer programming, or equivalent
  • Certifications like Learn JavaScript by W3Schools, CIW JavaScript Specialist course, and JavaScript certification by International JavaScript Institute
  • Online YouTube and LinkedIn tutorials for programmers, such as Learn JavaScript (full course for beginners), JavaScript Programming, and JavaScript Code Challenges

Getting your freelance career rolling as a JavaScript developer can be difficult. But, with these additional resources, you can jumpstart your freelance career on the Upwork job market, and you can even land your first job opportunity in no time:
