Why JavaScript - and why sometimes not

Where the JS ecosystem shines

One language stack from browser to server - less friction, faster teams.
TypeScript catches errors before they go live - and documents on the side.
Huge ecosystem: a proven tool exists for almost every problem.
Our preferred combination: React, Node.js, modern build tools.

Honestly: where it does not fit

Compute-heavy backends: Go, Rust or PHP workers are often the better pick.
Plain JavaScript without types? A maintenance risk in team projects - we write TypeScript.
Sprawl looms: without architecture the ecosystem becomes a trap.

Exactly this trade-off is what we work through in the free first consultation - before a single line of code.

Our JavaScript is TypeScript: strict types, ESLint, tests, CI - the same care as in any other stack.

Migration

From the jQuery era into the present.

Grown jQuery and vanilla frontends make every change expensive. We modernise step by step: structure and types first, then framework - no big bang.

Frequent questions

JavaScript or TypeScript?

TypeScript - in every team project. The onboarding costs days, the types save months. We migrate existing JavaScript incrementally.

Can you take over our grown frontend code?

Yes: audit, cleanup plan, modernisation in running operation. We tell you honestly what is salvageable and what is cheaper to rebuild.

Which frameworks do you use?

React and Next.js as standard, Vue/Nuxt and Angular depending on existing code and needs. The language underneath is always TypeScript.
