some

Callable

• some<T>(xs: Traversable<T, unknown>, predicate: (x: T) => boolean): boolean

---

• The function tests whether any elements in the Traversable satisfy the predicate.

  Example

  any([true, true, true], identity)
  // => true
  
  any([10, 11, 5], x => x > 10)
  // => true
  
  any([true, false, true], identity)
  // => true
  
  any(false, false, false], identity)
  // => false
  
  all([], identity)
  // => true

  • Lodash - some
