The TypedArray.of() method creates a new typed array from a variable number of arguments. This method is nearly the same as Array.of().
TypedArray.of()
Try it
Syntax
TypedArray.of(element0) TypedArray.of(element0, element1) TypedArray.of(element0, element1, /* ... ,*/ elementN)
Where TypedArray is one of:
Parameters
-
elementN -
Elements of which to create the typed array.
Return value
A new TypedArray instance.
Description
Some subtle distinctions between Array.of() and TypedArray.of():
- If the
thisvalue passed toTypedArray.of()is not a constructor,TypedArray.of()will throw aTypeError, whereArray.of()defaults to creating a newArray. -
TypedArray.of()uses[[Put]]whereArray.of()uses[[DefineProperty]]. Hence, when working withProxyobjects, it callshandler.setto create new elements rather thanhandler.defineProperty().
Examples
Using of()
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); // Int16Array [ 0 ]
