The TypedArray.of() method creates a new typed array with a variable number of arguments. This method is nearly the same as Array.of().
TypedArray.of(element0[, element1[, ...[, elementN]]]) where TypedArray is one of: Int8Array Uint8Array Uint8ClampedArray Int16Array Uint16Array Int32Array Uint32Array Float32Array Float64Array
elementNA new TypedArray instance.
Some subtle distinctions between Array.of() and TypedArray.of():
this value passed to TypedArray.of is not a constructor, TypedArray.of will throw a TypeError, where Array.of defaults to creating a new Array.TypedArray.of uses [[Put]] where Array.of uses [[DefineProperty]]. Hence, when working with Proxy objects, it calls handler.set to create new elements rather than handler.defineProperty.Uint8Array.of(1); // Uint8Array [ 1 ]
Int8Array.of('1', '2', '3'); // Int8Array [ 1, 2, 3 ]
Float32Array.of(1, 2, 3); // Float32Array [ 1, 2, 3 ]
Int16Array.of(undefined); // IntArray [ 0 ]
