js object some

By TC5550 on May 23, 2020

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

By Dangerous Dogfish on Aug 02, 2020

// an array
const array = [ 1, 2, 3, 4, 5 ];

// check if any of the elements are less than three (the first two are)
array.some(function(element) {
	return element < 3;
}); // -> true
// ES6 equivalents
array.some((element) => {
	return element < 3
}); // -> true
array.some((element) => element < 3); // -> true
