Example
Functions
Reusable blocks of code that perform specific tasks
function greet(name) { console.log(`Hello, ${name}!`); } greet(“Alice”);
Conditional Statements
Control flow structures that make decisions based on conditions
let age = 18; if (age >= 18) { console.log(“You are an adult.”); } else { console.log(“You are a minor.”); }
Loops
Structures that allow you to repeatedly execute a block of code
for (let i = 0; i
