Answer
To avoid problems related to hoisting, always declare variables at the top of their scope using let or const instead of var. This ensures that variables are block-scoped and not hoisted to the top of their containing function or global scope. Additionally, declare functions before they are called to avoid issues with function hoisting.
js
// Use let or const
let x = 10;
const y = 20;
console.log(x, y); // Output: 10 20
// Declare functions before calling them
function myFunction() {
console.log("Hello, world!");
}
myFunction(); // Output: 'Hello, world!'
