Should you use jQuery or React?

The tl;dr is, it depends!

⭐️ 👀 2023 WEB DEVELOPMENT BOOTCAMP starting in days! Join the waiting list to reserve your spot in my 10-weeks cohort course and learn the fundamentals, HTML, CSS, JS, Tailwind, React, Next.js and much much more! 👀 ⭐️

First, you might not need jQuery at all, and just use the Web Platform APIs, but this is another story.

Let’s focus on the question. Should you use jQuery or React?

My answer is this. If you are building a Single Page Application, React is the obvious choice. React was built for this, and will take care of generating the views and rendering the elements in the page without you having to even think about the DOM, aka the nitty-gritty details of how to present the content on the page.

React follows a declarative approach, and using it you can work at a much higher level.

jQuery (or the native browser APIs) should not really be used when building an SPA, as things might get complicated very quickly.

It’s best suited at adding interactive parts to a page that’s most likely server-rendered, although it can co-exist within a React app.

With jQuery you interact directly with the DOM to select elements, using selectors to find the thing in the page you want to act upon.

It’s both much lower level, and more prone to complications as the size of your application grows.

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.
