What's React?
React is a JavaScript library that lets you build user interfaces or UIs.
React is popular because:
- Built for user interfaces
- Quick to load
- Open source
Getting to Know React, and Your Class Project
Rendering - the process of running the code you've written to create elements of the visual UI.
Virtual DOM - a lightweight JavaScript representation of the Document Object Model (DOM) used in declarative web frameworks such as React, Vue. js, and Elm. As the name implies, the virtual DOM is a much lighter replica of the actual DOM in the form of objects. The virtual DOM can be saved in the browser memory and doesn’t directly change what is shown on the user’s browser.
Open Source - content and code that anyone has access to download and modify at no financial cost.
