// Your first JavaScript code
console.log("Hello, JavaScript World!");


             Hello, JavaScript World!

📝

Variables, data types, and syntax

let name = "John";
console.log(name);

🔧

Create reusable blocks of code

function greet() {
  return "Hello!";
}

🎯

Make web pages interactive

document.getElementById("demo")
  .innerHTML = "Changed!";

⚡

Respond to user interactions

button.onclick = function() {
  alert("Clicked!");
};

See what JavaScript can do:

// Change text when button is clicked
function changeText() {
    document.getElementById("demo").innerHTML = "Text Changed!";
}

// Add two numbers
let a = 5;
let b = 3;
let result = a + b;
console.log("5 + 3 = " + result);


           5 + 3 = 8

// Display current date
let now = new Date();
console.log("Today is: " + now.toDateString());
