How do we add JavaScript to HTML?
There are 3 primary methods:
What is the difference between 'let' and 'const'?
It comes down to Re-assignment.
let age = 25;
age = 26; // ✅ Allowed
const country = "India";
country = "USA"; // ❌ Error!
What is the DOM?
The Document Object Model is the browser's way of turning HTML into an object tree that JavaScript can talk to.
document.getElementById("title").innerText = "Updated!";
