We all have used find before on an array, but what if we wanted to start from the end of the array? Well, thanks to findLast you no longer need to perform some weird logic or use an external library to pull this off.

In this example, you can see how findLast works the same way as find the only difference is that it starts from the end of the array.

const numbers = [5, 10, 15, 20, 25]

// Find starts from the begining
const n = numbers.find(num => num > 10)
console.log(n) // 15

// Find Last starts from the end
const n = numbers.findLast(num => num > 10)
console.log(n) // 25

Other than IE, you can use findLast in all major browsers. Check the browser compatibility list for more info.
