TypedArray.of()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2016.
The TypedArray.of()
static method creates a new
typed array from a variable number of arguments. This method is nearly the same as
Array.of()
.
Try it
Syntax
js
TypedArray.of()
TypedArray.of(element1)
TypedArray.of(element1, element2)
TypedArray.of(element1, element2, /* …, */ elementN)
Where TypedArray
is one of:
Parameters
element1
, …,elementN
-
Elements used to create the typed array.
Return value
A new TypedArray
instance.
Description
See Array.of()
for more details. There are some subtle distinctions between Array.of()
and
TypedArray.of()
:
- If the
this
value passed toTypedArray.of()
is not a constructor,TypedArray.from()
will throw aTypeError
, whileArray.of()
defaults to creating a newArray
. TypedArray.of()
uses[[Set]]
whileArray.of()
uses[[DefineOwnProperty]]
. Hence, when working withProxy
objects, it callshandler.set()
to create new elements rather thanhandler.defineProperty()
.
Examples
Using of()
js
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 ]
