How much could you earn as a JavaScript developer? Let’s find out!

1. What is a JavaScript developer?

First things first: What exactly are these kinds of developer?

Together with HTML and CSS, JavaScript is one of the cornerstone technologies of the web. In very simplistic terms, it is a programming language used to add interactivity to a webpage. JavaScript is an integral part of web functionality, and is therefore supported across all web browsers and tools.

JavaScript developers are, of course, experts in JavaScript—but what does that actually mean in terms of day-to-day tasks?

Essentially, they are responsible for implementing the frontend logic that defines how the visual elements of a web app behave. Typically these developers typically work on the frontend, supported closely by backend developers and other frontend developers who specialize in markup and styling. You can learn all about the difference between frontend and backend development in this guide.

To gain a better overview of what a career as a JavaScript developer entails, let’s consider some real-world job descriptions.

JavaScript developer job descriptions

A search on LinkedIn for “JavaScript developer jobs” in the United States returns over 7,000 results. To give you an idea of what someone in this role actually does, we’ve taken a few snippets from some live job ads.

Our first example is a job ad posted by Apple, which describes the JavaScript developer role as follows:

Under key qualifications, they ask for a deep understanding of frontend JavaScript development together with expertise in JavaScript libraries such as ReactJS and Redux. Desirable skills include experience with MySQL and scripting in Python and Perl.

Our second example was posted by Grand Canyon Education, Inc. Here’s how they describe the role:

2. Are JavaScript developers in demand?

If you’re considering a career as a JavaScript developer, you’ll be pleased to hear that JavaScript is one of the most sought-after skills in the programming industry today.

In their Global Technical Hiring & Skills Report 2020, recruiting platform Devskiller unveiled some interesting insights into current developer hiring trends. Based on their analysis of over 200,000 coding tests in 143 countries, they found that 72% of companies are looking to hire JavaScript developers.

A report by HackerRank, meanwhile, found that the global demand for JavaScript outweighs the expertise available on the market. According to the report, 53.6% of employers worldwide say they need JavaScript skills, yet only 42% of student developers say they are proficient in the language.

So, if you plan on becoming a JavaScript expert, you can expect to be highly employable.

3. JavaScript developer salaries around the world

So far, we know that these kinds of programmer are in demand—but what’s the earning potential behind this sought-after job title?

Based on the most recent salary data available, here’s what JavaScript developers are earning around the world:

  • Australia: $112,229 per year (Indeed)
  • Canada: $82,786 per year (Indeed)
  • Germany: €58,108 per year (Glassdoor)
  • India: ₹ 5,18,875 per year (Indeed)
  • South Africa: R 472 710 per year (Indeed)
  • United Kingdom: £49,001 per year (Indeed)
  • United States: $111,069 per year (Indeed)

Location is not the only factor that affects your salary. Next, we’ll look at these salaries based on years of experience.

4. JavaScript developer salaries by city

While it’s all well and good getting a little slice of what the pay outlook is like worldwide, it’s even more useful to drill down a little more. Examining how much programmers fluent in JS can expect to earn on a city-by-city basis can give you a more accurate picture. So with that, let’s take a look in a selection of major cities on both sides of the Atlantic, using salary data from Glassdoor.

North American JavaScript developer salaries

  • Austin: $91,788
  • Boston: $120,816
  • Chicago: $86,393
  • Houston: $89,750
  • Los Angeles: $122,829
  • Montreal: CA$77,000 ($60,949)
  • New York: $92,102
  • Philadelphia: $91,219
  • Phoenix: $91,893
  • Portland: $103,688
  • San Francisco: $102,220
  • Seattle: $104,812
  • Toronto: CA$72,000 ($59,366)
  • Washington DC: $107,505
  • Vancouver: CA$87,000 ($68,864)

As you can see, JavaScript developers can find themselves earning a cool six figures in some major US cities such as Portland and Washington DC, while it’s perhaps a little surprising that they stand to earn more in Los Angeles and Boston than in New York and San Francisco, which typically command higher tech wages. Again, more demand for other coding languages or skillsets can explain this, so it’s useful to compare with full-stack developer salaries to get more of an idea.

Now that we’ve covered that continent, let’s take a trip east across the ocean to see the state of average JavaScript developer salaries in Europe.

JavaScript developer salaries by European city

We’ve collected the average salary data from Glassdoor for various large European cities so that you can easily see what to expect. If you’d like to check the dollar equivalent, a simple currency calculator will do that for you.

  • Amsterdam: €55,862
  • Barcelona: €30,582
  • Berlin: €51,907
  • Brussels: €28,704
  • Dublin:56,978
  • Hamburg: €57,312
  • Lisbon: €15,972
  • London: £58,713 (€68,977)
  • Madrid:26,942 
  • Munich:66,748
  • Paris:42,625
  • Rome: €38,978

Even more than in North America, it’s important to consider here the cost of living in each city when looking at whether it’s the one that you’d like to start applying for JavaScript developer salaries in. Earning just under £60,000 in an expensive city like London could provide a lower standard of living than earning €38,000 in a more reasonable city such as Rome.

5. JavaScript developer salaries based on years of experience

As with most career paths, you can expect your salary to increase as you gain more experience in the field. With the help of PayScale’s salary data, we’ve put together a snapshot of average JavaScript developer salaries in the United States based on years of experience.

  • Less than 1 year of experience: $62,973 per year
  • 1-4 years: $70,022 per year
  • 5-9 years: $87,281 per year
  • 10-19 years: $102,697
  • 20 years or more: $113,274

6. JavaScript developer salaries based on company size

To round off our salary report, we investigated whether company size also has an impact on how much you can earn as a JavaScript expert in the United States. Once again, we’ve referred to the most recent data available on PayScale.

  • 1-9 employees: $73,202
  • 10-49 employees: $72,081
  • 50-199 employees: $78,114
  • 200-599 employees: $81,377

  • 2,000-4,999 employees: $84,738
  • 5,000-19,999 employees: $89,866
  • 20,000-49,999 employees: $88,860
  • 50,000+ employees: $88,650

Perhaps unsurprisingly, larger companies tend to pay developers specializing in this language a slightly higher salary. However, whether you choose to work for a small startup or a major corporation, you can expect a competitive rate of pay as a JavaScript expert.
