JavaScript developers
who know which runtime they're actually writing for.

What moves the number most is scope, not the language itself: a front-end feature against an existing API is smaller than a full-stack build with a new data layer, and a dedicated engineer joining your team on an ongoing basis is priced differently than a fixed-scope project with a defined end date.

The other real driver is how much existing code has to be understood before new work starts — a clean, tested codebase is faster to build on than one with no tests and undocumented dependencies. A short scoping call is the fastest way to get an actual number for your specific project rather than a guess from a generic range.

Other than sharing part of a name — a 1995 marketing decision, not a technical relationship — JavaScript and Java are different languages built for different jobs. JavaScript is interpreted and runs primarily in the browser (and, via Node.js, on servers); Java is compiled and runs primarily on servers, in enterprise backends, and on Android.

They don't share a standard library, a type system, or a runtime. If a job posting or a project brief conflates the two, that's worth clarifying before any scoping conversation goes further.

For anything beyond a small script, yes. TypeScript adds a compile-time type system on top of JavaScript, which catches an entire category of bugs — passing the wrong shape of data into a function, forgetting to handle a null value — before they reach production instead of after.

The cost is a small amount of upfront ceremony and a learning curve for developers new to it. That cost is far lower than retrofitting types onto a codebase that's already grown past a few thousand lines, which is why we default to TypeScript on anything with an expected lifespan past a few months.

React has the largest ecosystem and hiring pool, and is the safest default for interaction-heavy interfaces where you expect to need a library for nearly anything. Vue and Svelte are genuinely competitive alternatives with smaller communities but less boilerplate — Svelte in particular ships less runtime JavaScript to the browser. Angular is a more opinionated, batteries-included framework that tends to fit larger, structured enterprise applications better than a small product.

For a lot of pages — marketing sites, documentation, content that doesn't need heavy client-side interactivity — the right answer is no framework at all. We'll recommend based on what the interface actually needs to do and who's going to maintain it, not on which option is generating the most conference talks this year.

Yes — that's what Node.js is. It's a JavaScript runtime built on Chrome's V8 engine that runs outside the browser, which lets a team build APIs, background jobs, and full backend services in the same language as the front end.

The advantage is one language and, with TypeScript, shared types across the API boundary — a change to a data shape on the backend can be caught at compile time on the front end instead of discovered at runtime. It isn't the right choice for every backend workload, particularly CPU-heavy processing, but for most web application backends it's a mature, well-supported option.

We agree on a real browser-support matrix at the start of a project — which browsers and versions your actual users are on — rather than defaulting to supporting everything, which quietly bloats every page with polyfills nobody needs. Build tooling (Babel, or a modern bundler's built-in transforms) then handles the gap between the JavaScript we write and what older browsers can run natively.

We test against that agreed matrix, not just against whatever browser happens to be open on a developer's laptop, which is where most compatibility bugs actually slip through.

Yes. A dedicated senior JavaScript, Node.js, or full-stack engineer can join your existing team, sprint cadence, and codebase directly — attending your standups and working in your repository rather than operating as a separate outside project. It's often the better fit for ongoing feature work on a product you already run, as opposed to a fixed-scope build with a defined start and end.
