Variables

Variables store data. In modern JavaScript we use let and const:

let name = "Bethwel"; // can change
const PI = 3.14; // cannot change

console.log(name); // prints: Bethwel

Data Types

• String — text in quotes: "hello"
• Number — 42, 3.14
• Boolean — true or false
• Array — [1, 2, 3]
• Object — {name: "Merik", age: 2}

Task

Create variables for your name, age, and favorite language. Display them on the page!
