JavaScript Framework.
A JavaScript framework is a structured codebase that provides developers with pre-built tools and conventions for web development. React, Vue, Angular, and Svelte are the most well-known frameworks for modern frontend development.
JavaScript Framework — Explained in Detail
A JavaScript framework (or library) provides developers with a foundation and pre-built functions to build web applications efficiently. Instead of programming everything from scratch, developers use proven patterns for UI rendering, state management, routing, and API communication. The dominant frameworks in 2026: React (by Meta, market leader), Vue (popular in Europe), Angular (by Google, for enterprise), and Svelte (rising, compiles to vanilla JS).
The choice of framework has a major impact on performance, development speed, SEO, and maintainability. React (with Next.js) offers the largest ecosystem and the best developer availability. Vue is more beginner-friendly and popular with small teams. Angular is ideal for complex enterprise applications. Svelte generates the leanest code and offers the best runtime performance — but is still less widely adopted.
For Swiss SME websites, DLM Digital recommends React with Tailwind CSS: the largest ecosystem of components and tools, the best performance with Server-Side Rendering (SSR) and Static Site Generation (SSG), excellent SEO compatibility, and the broadest developer availability in the Swiss market. For interactive landing pages, we additionally use GSAP (GreenSock) for animations.

Web DevelopmentFrequently Asked Questions About JavaScript Framework
There is no 'best' framework — it depends on the project. For most SME websites: React (with Next.js) — largest ecosystem, best SEO support, broadest developer availability. For smaller projects with simple interactivity: Vue or Svelte. For large enterprise applications: Angular. DLM Digital primarily uses React with Tailwind CSS.
By default, Client-Side Rendered (CSR) JavaScript apps are poor for SEO, as Google can only see the content after JavaScript execution. The solution: Server-Side Rendering (SSR) or Static Site Generation (SSG) — frameworks like Next.js (React) or Nuxt (Vue) support both. This way, the HTML page is rendered server-side and Google can see the content immediately.
Technically, React is a 'library': it provides UI rendering functions but doesn't dictate how you handle routing, state management, etc. A framework like Angular or Next.js prescribes the structure — 'Inversion of Control'. In practice, React is often referred to as a framework, since with the React ecosystem (Next.js, React Router, Zustand) it functions like one.
