Introduction to React

React is a JavaScript library for building user interfaces. It allows developers to create large web applications that can change data without reloading the page.

React vs Angular

• React is a Library (developed in JS) while Angular is a Framework (developed in TypeScript)
• React development and performance is faster than Angular
• React uses a virtual DOM to improve performance
• React has less memory consumption/footprint
• React has a less steep learning curve than Angular
• React doesn't enforce a specific architecture, while Angular has a predefined architecture and tooling

Single Page Application (SPA)

An application that loads a single HTML page and dynamically updates that page as the user interacts with the app.

Advantages of SPAs

• Fast: Similar performance to native apps
• Responsive: The app responds to user interactions (browser size changes)
• User-friendly

Functional Programming in JavaScript

• Functions are considered first-class citizens
• Functions can be created as variables of type function
• Functions can be passed as arguments to other functions
