JavaScript Basics
Learn the fundamental concepts of JavaScript programming
Course Overview
This course covers the fundamental concepts you need to start programming in JavaScript. Each section builds upon the previous one, so we recommend following them in order.
1. Variables and Constants
Section 1Think of variables as labeled boxes where you can store information. Just like you might label a box "toys" or "books", you can create variables with names that describe what they contain.
2. Data Types
Section 2Every piece of information in JavaScript has a "type" - just like in real life where we have different types of things: numbers, words, yes/no answers, etc.
3. Basic Operations
Section 3Now that you can store data, let's learn how to work with it! JavaScript can perform calculations and combine information in useful ways.
4. Console Output
Section 4The console is like a message board where your program can display information. It's incredibly useful for understanding what your code is doing!
