Code Structure

JavaScript code runs from top to bottom, line by line. 

Each line of code is a command (also called a statement) that tells the computer what to do.

console.log("Hello!") // First command
console.log("How are you?") // Second command

In JavaScript, you can end each command with a semicolon (;), but it’s not required. The computer understands your code with or without it.

Both examples below work the same:

console.log("Semicolon is here!"); // With ;
console.log("No semicolon here!")  // Without ;

But adding semicolons is a good habit to avoid mistakes!
