How can I use the filter method in real-world applications?

The filter method is great for creating a new array with elements that pass a certain condition. For example, if you have an array of numbers and want to get only the even ones, you can use filter.

Can you show me a code example?

Sure! Here's a simple example in JavaScript:

const numbers = [1, 2, 3, 4, 5, 6];
const evenNumbers = numbers.filter(num => num % 2 === 0);
console.log(evenNumbers); // Output: [2, 4, 6]

What other scenarios can I use the filter method for?

You can use it for filtering user data, products in an inventory, or even filtering out invalid entries from a form.
