    React Essentials: From jQuery Chaos to Modern Web

    Best quote from 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.

    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.
