Most frontend adverts we studied, from Accra fintechs to remote agencies, name a framework, and React was by far the most common, often paired with TypeScript. Frameworks help teams build large interfaces in an organised way. This section introduces them once plain JavaScript feels comfortable.
Why frameworks exist
With plain JavaScript, you find elements and update them by hand. That works for a small page. In a big app with many screens, keeping the page in step with changing data becomes messy and bug prone.
Frameworks such as React let you describe what the screen should look like for the current data. When the data changes, the framework updates the page for you. You think in components: small, reusable pieces like a ProductCard, a PriceTag or a MomoCheckout button.
What this section covers
- React fundamentals: components, props and state, the core ideas employers test.
- TypeScript basics: adding types to JavaScript so mistakes show up before users see them.
- A full stack framework such as Next.js (optional): routing, server rendering and data loading on top of React.
