any
Returns true
if the provided predicate function returns true
for at least one element in a collection, false
otherwise.
Use Array.prototype.some()
to test if any elements in the collection return true
based on fn
.
Omit the second argument, fn
, to use Boolean
as a default.
typescript
const any = <T = any>(arr: T[], fn: (t: T) => boolean = Boolean) =>
arr.some(fn);
typescript
any([0, 1, 2, 0], (x) => x >= 2); // true
any([0, 0, 1, 0]); // true
