how to return a value of an array that pass a test in javascript 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
