React and Next.js

We build with Angular, but React is what we see most in job listings, in projects that come to us for maintenance and in startups that need to move fast. Its model is simple to explain and hard to master: components that are functions, state that triggers renders and hooks with rules that do not forgive. Next.js adds what React leaves out: routing, server rendering and a clear way for search engines to index your app. We chose courses that teach React with function components and hooks, and Next.js with the App Router, because much of the material out there still uses classes or the Pages Router, and that shows the moment you join a current project. We also looked for courses that build an app end to end, with real data and deployment. There are Spanish-language options to get started and English reference courses, which tend to update first.

Who it is for

• People who already know JavaScript and want a first framework with broad job prospects.
• Developers who inherit a React project and need to understand it before changing it.
• Teams that need SEO or fast load times and are evaluating Next.js.

What you will learn

• Components, props and composition: how to split a screen without ending up with thousand-line components.
• Hooks: useState, useEffect and why so many React bugs live in a badly written effect.
• State management: when local state is enough, when to use context and when to reach for a library.
• Next.js: routing, server components and rendering strategies.
• Technical SEO and performance: metadata, server-side data loading and metrics such as LCP.

Recommended order

1. Modern JavaScript first. Much of what feels hard in React is JavaScript that was never solid.
2. Plain React with components and hooks, building a small app with nothing on top.
3. State and API consumption, once the app has several screens sharing data.
4. Next.js last, to take it to production with server rendering and SEO.

Frequently asked questions

How long does it take to learn React?

If you already know JavaScript, React basics take a few weeks. Feeling comfortable with state, effects and a multi-screen app usually takes two or three months of practice. Without solid JavaScript, it takes considerably longer.

React or Angular to start with?

React if you want more job openings and freedom to assemble your own stack; Angular if you will work on large business applications that value an enforced structure. At TintoDev we use Angular for that structure, but both are solid choices, and what counts is mastering one in depth.

Do I need to learn React before Next.js?

Yes. Next.js is a framework built on React, and its concepts (server components, routing, data loading) assume you already understand components and hooks. Starting straight with Next.js means climbing two learning curves at once.

Is React useful for getting a job in Latin America?

Yes, it is one of the most requested frontend skills in the region, at local companies and in remote work for foreign clients. It helps to arrive with TypeScript and at least one deployed project, since both tend to come up in hiring processes.

Are there React courses in Spanish?

Yes. The catalogue mixes Spanish and English courses, and each listing shows the course language. Check the last update date as well: in React and Next.js, a course from a few years ago can teach patterns that are no longer used.
