Uint8Array.prototype.some

Determines whether the predicate function returns true for any element of a typed array.

Syntax

some(predicate, thisArg?)

Parameters

• predicate function(value, index, array)

  A function that accepts up to three arguments. The some method calls the predicate function for each element in the array until the predicate returns a value which is coercible to the Boolean value true, or until the end of the array.

• thisArg? optional

  An object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.

Return value

Returns true if a predicate returns true for any element, false otherwise.

Example

new Uint8Array([4, 5, 6]).some(x => x % 2 === 0)

true

new Uint8Array([1, 3, 5]).some(x => x % 2 === 0)

false
