programming language of the web

JavaScript in 30 seconds

JavaScript is the programming language of the web, standardised as ECMAScript, and the only language browsers run natively. Node.js extends it to servers, command-line tools and build systems.

Nearly every interactive interface on the web is JavaScript at some level, whether written directly or produced by TypeScript, a framework or a build pipeline.

What a JavaScript developer actually works on

  • Interactive front ends, from a single widget to a full application
  • Server-side APIs and background jobs on Node.js
  • Build tooling, scripts and automation around an existing codebase

What to check before you hire a JavaScript developer

  • Asynchronous behaviour: promises, the event loop, and how they debug a race condition
  • Modern language features and why they still matter after a framework abstracts them
  • Whether they can work in plain JavaScript when a project has no framework at all

Is JavaScript the right call?

JavaScript is not going anywhere, and most professional work now runs through TypeScript. Ask which framework and which runtime, because the label alone says very little about fit.

Paste the template below into your job board or careers page, then replace the bracketed placeholders with your company's specifics. Every section is written to be edited, not just admired.

About the role [Company] builds [product] on a JavaScript stack end to end: [framework] in the browser, Node.js on the server, TypeScript throughout. We are hiring a JavaScript Developer who has the fundamentals to work anywhere in that surface and the depth to own part of it. What you will do - Ship features across client and server in TypeScript. - Keep our app fast: performance budgets are part of done. - Improve the type coverage and test coverage that keep us moving. - Debug the weird stuff: race conditions, browser edge cases, leaky abstractions. - Help maintain conventions that keep a growing codebase readable. What we are looking for - 3+ years of production JavaScript with real TypeScript mileage. - Fundamentals that hold up without a framework as a crutch. - Depth in [framework] and honest competence in Node. - Testing and review habits that raise team quality. - Clear written communication. Nice to have - Build tooling expertise, open-source work, or full-stack ownership experience. Compensation and benefits Base salary of $95,000 to $170,000 depending on experience, plus [equity/bonus] and benefits. Adjust the range for your market before posting. How we work Our stack is consistent enough to master and varied enough to stay interesting. You will rotate across client and server work by inclination, not assignment, with a [learning budget], hardware of your choice, and retrospectives honest enough to change how the next cycle runs. How to apply Send a resume and a link to code or a product you built. One paragraph about the nastiest JavaScript bug you have fixed is our favorite cover letter.

Frequently asked questions

Should we post for JavaScript or for our specific framework?

Post the framework if the role lives in it; post JavaScript when the work spans client, server, and tooling. Either way, require TypeScript, which has become the professional default.

What do JavaScript developers earn in the US?

Base salaries typically run $95,000 to $170,000. The contractor market is wide, roughly $35 to $130 per hour, because the talent pool spans bootcamp graduates to platform experts.

How do we filter a large JavaScript applicant pool efficiently?

Screen for fundamentals early: a short exercise on async behavior or state management eliminates surface-level candidates faster than resume review, and vetted marketplaces pre-filter for you.

Vanilla JavaScript questions or framework questions in interviews?

Both, in that order. Fundamentals predict long-term adaptability; framework depth predicts short-term productivity. A candidate strong in only one is a situational hire.
