Leírás

A logikai értéket ad vissza, ha a tömb legalább egy eleme teljesíti a feltételt. A some nem iterál tovább amennyiben talált egy elemet, ami megfelel a feltételnek.

Szintaxis

some(callbackFn)
some(callbackFn, thisArg)

Példa

const array = [1, 2, 3, 4, 5]
 
// Checks whether an element is even
const even = (element) => element % 2 === 0
 
console.log(array.some(even))
// Expected output: true
