javascript includes predicate code example

Example 1: javascript array some

let array = [1, 2, 3, 4, 5];

//Is any element even?
array.some(function(x) {
  return x % 2 == 0;
}); // true

Example 2: js object some

let obj = {"num1":1, "num2":2, "num3":3, "num4":4, "num5":5};

var firstEven = null;

// Some returns a boolean value.
Object.values(obj).some((item) => {
	// Loop breaks as soon as the condition has been met.
  	// Getting your value, can be used like:
  	if	(item == 2) {
		firstEven = item;
	}
	return item % 2 == 0;
}); // Results in true
