What are some examples of using the filter method in JavaScript arrays?

Can you explain how the filter method works in JavaScript?

Sure! The filter method creates a new array with all elements that pass the test implemented by the provided function.

Can you give me an example of using filter with an array of numbers?

Absolutely! For instance, if you have an array of numbers and want to filter out the even numbers, you can do this:

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

What if I want to filter objects in an array?

You can filter objects in a similar way. For example, if you have an array of objects representing people and want to filter by age:

const people = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];
const adults = people.filter(person => person.age >= 30);
console.log(adults); // Output: [{ name: 'Bob', age: 30 }, { name: 'Charlie', age: 35 }]
