What is find() Method?

The find() method can only be invoked on a Javascript array.

const ages = [3, 10, 18, 20, 25];
ages.find();

It’s one of the higher-order functions similar to map, reduce, filter, etc.

Any function that accepts or returns another function is called a higher-order function.

Apparently, find() will only take a function as an argument that is required.

How Does Find() Method Work?

The find() method will search for the very first element from a given Javascript array until the condition we specify is met or satisfied.

Then…

It will exit & ignore everything else including the second element that meets the condition.
