What is React?

React is a JavaScript library that aims to simplify development of visual interfaces.

Developed at Facebook and released to the world in 2013, it drives some of the most widely used apps, powering Facebook and Instagram among countless other applications.

Its primary goal is to make it easy to reason about an interface and its state at any point in time, by dividing the UI into a collection of components.

React has taken the frontend web development world by storm. Why?

Less complex than the other alternatives

At the time when React was announced, Ember.js and Angular 1.x were the predominant choices as a framework. Both these imposed so many conventions on the code that porting an existing app was not convenient at all. React made a choice to be very easy to integrate into an existing project, because that’s how they had to do it at Facebook in order to introduce it to the existing codebase. Also, those 2 frameworks brought too much to the table, while React only chose to implement the View layer instead of the full MVC stack.

Perfect timing

At the time, Angular 2.x was announced by Google, along with the backwards incompatibility and major changes it was going to bring. Moving from Angular 1 to 2 was like moving to a different framework, so this, along with execution speed improvements that React promised, made it something developers were eager to try.

Backed by Facebook

Being backed by Facebook obviously is going to benefit a project if it turns out to be successful.

Facebook currently has a strong interest in React, sees the value of it being Open Source, and this is a huge plus for all the developers using it in their own projects.

Is React simple to learn?

Even though I said that React is simpler than alternative frameworks, diving into React is still complicated, but mostly because of the corollary technologies that can be integrated with React, like Redux and GraphQL.

React in itself has a very small API, and you basically need to understand 4 concepts to get started:

One more thing! ⚠️ ✋

At the end of January I will organize the Web Development Bootcamp.

It's a 10-weeks long cohort online course where I will guide you to becoming a Web Developer.

It's not "just a course". It's a big event I organize once a year.

We'll start from zero, learn the fundamentals of Web Development, HTML CSS, JavaScript, Tailwind, Git, using the command line, VS Code, GitHub, Node.js, we'll then learn React, JSX, how to use PostgreSQL, Astro, Next.js, Prisma, deploying on Netlify/DigitalOcean/Fly/Vercel and much more! 

At the end of the first 10 weeks you'll know how to create web sites and web applications and I'll unlock you the 2nd phase of the Bootcamp: you will get access to a large number of projects exclusive to the Bootcamp graduates, so you can follow my instructions to build things like private areas with authentication, clones of popular sites like Twitter YouTube Reddit, create e-commerce sites, and much much more.

Because once you got the fundamentals, you only learn by working on real, exciting projects.
