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
this
value 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 withProxy
objects, it callshandler.set
to 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 ]
