    React Essentials: From jQuery Chaos to Modern Web

    Meilleure citation de React Essentials: From jQuery Chaos to Modern Web

    “

    React breaks applications into reusable components, manages state effectively, and uses a 'virtual DOM' to make updates super efficient, changing the approach from imperative to declarative programming.

    Question posée

    I want to learn react, but basics only. Start from the history why the react was build, how people used to do earlier with JavaScript ajax, then node and express and finally react. Then teach me basics of the react step by step. Explain jargons used. Make it in depth.

    From jQuery Chaos to React Revolution

    0:00

    Lena: Hey there, welcome to today's episode! I've been diving into web development lately, and I keep hearing about React everywhere. It seems like every job posting mentions it. What's the big deal with React anyway?

    0:12

    Jackson: That's a great question, Lena. React has become incredibly popular, and for good reason. You know, before React came along in 2013, web development was in a pretty chaotic state. Imagine trying to manage thousands of lines of JavaScript code for websites like Facebook or Netflix!

    0:29

    Lena: Oh, I can't even imagine. So what was happening before React? How were developers building websites?

    0:36

    Jackson: Well, back in the early days of the web, sites were mostly static pages. Then jQuery came along around 2006 and was revolutionary for its time. But as websites grew more complex, those jQuery files became unmanageable.

    0:50

    Lena: Right, I've heard about jQuery. So React was created to solve that problem?

    0:56

    Jackson: Exactly! Facebook developed React to address several key challenges. It breaks applications into reusable components, manages state effectively, and uses something called a "virtual DOM" to make updates super efficient. It's fascinating how React completely changed the approach from imperative to declarative programming.

    1:15

    Lena: Declarative programming? That sounds technical.

    1:18

    Jackson: It just means instead of telling the computer exactly how to do something step by step, you simply declare what you want to happen. It's like the difference between giving someone turn-by-turn directions versus just saying "meet me at the coffee shop."

    1:32

    Lena: That makes sense! So React is basically a bunch of JavaScript that someone else wrote to make our lives easier when building complex websites?

    1:41

    Jackson: That's a perfect way to put it! Let's dive into how React actually works and see how it revolutionized the way we build for the web.
