How to become a senior JavaScript developer

Demand for JavaScript developers is enormous, and new opportunities arise every day

Many programming and developing careers have peaks and inevitable declines. Eventually, it gets harder to find and keep a job as a programmer in tomorrow’s job market. However, that’s not quite the case with JavaScript developers.

Current times favor developers and programmers, as companies big and small worldwide are always in search of them. According to the LinkedIn 2020 Emerging Jobs Report, JavaScript developer is the 14th most in-demand emerging job in the U.S. with 25% annual growth.

Even better, the latest research suggests that JavaScript goes into the development of 96.5% of all websites and will continue to do so. Additionally, in the Stack Overflow Developer Survey 2019, JavaScript was the most commonly used programming language.

Many JavaScript developers’ goals are to eventually become a senior JavaScript developer. Increasing seniority will open a wide array of opportunities for you to work on new projects, exciting challenges and even allow you to move to a new company if you desire. But many developers don’t understand the expectations and job requirements included in being a senior JavaScript developer.

We’ll pull back the curtain and show a potential career path from the beginning as a junior JavaScript developer to the apex as a senior JavaScript developer. 

How to become a JavaScript Developer?

Though it’s possible to work as a JavaScript developer without formal qualifications, employers generally prefer individuals with qualifications in computer science. So, if your goal is to become a senior JavaScript developer, here is what you should do.

  • Obtain a qualification in computer science with a focus on software development. A bachelor’s degree in information technology or software development will fit the bill.
  • Secure an internship program while studying. An internship will help you gain relevant experience and mentorships from experienced developers.
  • Complete an online or in-person course in JavaScript.

JavaScript development career ladder

Before we dive any deeper, let's take a look at the various rungs in the JavaScript development career ladder. Between each rung is a transition phase that requires building knowledge and experience in a specific area.

Junior JavaScript developer

A junior JavaScript developer is someone who has just entered the field and works with a team of professionals to solve problems for an organization. 

Since JavaScript is primarily for front-end development, the JavaScript developer will most likely work on web applications to add additional functionality to the existing codebase or fixing an existing application.

Intermediate JavaScript developer

An intermediate JavaScript developer is a competent team member and contributor who’s learned the skills to build a basic system, like web applications or apps. At this stage, the developer will learn other skills, including:

  • Basic system architecture
  • Professional tooling use
  • Design patterns, code smells, etc.

Senior JavaScript developer

The senior JavaScript developer is highly skilled and knowledgeable to the point that other developers look up to them as a mentor. They usually possess a good track record of solving advanced problems and building more complex systems using advanced techniques.

A few other traits of senior JavaScript developer are:

  • Knowledge of design patterns, refactoring etc.
  • A solid understanding of architectural paradigms
  • Experience with server deployments and infrastructural maintenance

How to become a senior JavaScript developer

We’ve highlighted the various stages of your JavaScript development career. Now, we’ll look at the transitions through a developer’s career. 

From coder to junior JavaScript developer

A coder is a hobbyist who isn’t paid for coding but does it for pleasure in their free time. Essential traits of a coder include good knowledge of JavaScript, an in-depth understanding of syntax and a love for solving problems that arise in various smaller projects.

The transition from coder to junior JavaScript developer occurs when you enter the IT field and land your first paid position as a JavaScript developer. As a junior JavaScript developer, you will turn business requirements into applications and use tools to solve real-world problems.

If you are at this stage, you’re working with a team and an excel by becoming a great team member and learning as much as you can while on the job. Here’s what you should do to become a great team member and move forward in your career:

  • Clearly communicate your goals each workday instead of jumping right into technical specifics.
  • When working in codebases, which can be quite overwhelming, develop a strategy before touching the code. For example, try breaking down problems into small steps.
  • Keep an achievement log that allows you to document what that you’ve learned or complex problems you’ve solved. This log will be something to look back to if you have a slow or disappointing day. It will also help when it's time to revise your resume.
  • Read a wide range of books in your field, including subjects outside your comfort zone. Even senior JavaScript developers perform daily research.
  • Join a developer community, which are forums, Facebook groups or websites where you can interact with fellow Java developers to learn more about Java or seek help for a specific problem you are facing. You will also get to contribute to open-source projects and eventually attend conferences. A few Java forums you should visit regularly are StackOverFlow, Oracle Java Forum and Coderanch

From junior to intermediate JavaScript developer

The boundary between junior and intermediate JavaScript developer is a bit blurry. A telltale sign you’ve reached this level is when you feel like you know everything you need to know to architect a system. You may also feel like JavaScript is the only programming language you’ll ever need. 

This feeling isn’t a bad thing. In fact, it marks your growth as a JavaScript developer.

Intermediate developers take junior developer knowledge and skill to the next level, gaining more experience in the process. Some tips that’ll help you in this career point include:

  • Joining a high-visibility project to gain experience fast and build a reputation within your company.
  • Being ready to pounce on challenges that lie beyond your comfort zone to help build trust, confidence and a reputation.
  • Finding a good mentor who can reel you back when needed.
  • Continuing to learn and test new ideas and concepts. 

From intermediate to senior JavaScript developer

A senior developer is fluent in JavaScript and can handle high-level architectural concerns and designs. A senior JavaScript developer possesses years of experience building real-world web applications and mentoring other developers on their team. 

To become a senior JavaScript developer, you need lots of practice and experience to get accustomed to a variety of real-world problems and their solutions.

Here are some tips to being a successful senior JavaScript developer:

  • Find the tech stack, the list of all the technology services used to build and run a single application, you want to be skilled with and learn it in depth. 
  • Have the courage to take on challenging projects offered to you.
  • Step outside your comfort zone and work on varied projects — even those outside your expertise.
  • Keep track of your growing skills and determine the ones you’d like to expand upon.
  • Have a good understanding of design patterns and know what problems each pattern solves.
  • Ensure you’re always learning new things at your job. If it becomes stagnant, it may be time to move on.
