React Introduction
What is React?
React, sometimes called the frontend JavaScript framework, is a JavaScript library built by Facebook.
React is a tool for building UI components.
How does React Work?
React creates a VIRTUAL DOM in memory.
Instead of fooling the browser DOM directly, React creates a visual DOM in memory, where it performs all the necessary tricks, before making changes to the browser DOM.
Only response to changes that need to be changed!
React finds out what changes have been made, and only changes what needs to be changed.
You will learn various aspects of how React does this throughout the course.
