What is the find() method? in Javascript

/* This method returns first element of the array that satisfies the condition
	specified in the callback function.
*/

const x = [1, 2, 3, 4, 5];

const y = x.find(el => el*2 === 2);

console.log("y is: ", y); // y is: 1

/* Now, if you see the output of the above example, the value of y is 1.
	This is because the find() method searches for first element in the array
    that satisfies the condition specified.
*/
