Summary

+ +

The Uint16Array typed array represents an array of 16-bit unsigned integers in the platform byte order. If control over byte order is needed, use {{jsxref("DataView")}} instead. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

+ +

Syntax

+ +
Uint16Array(length);
+Uint16Array(typedArray);
+Uint16Array(object);
+Uint16Array(buffer [, byteOffset [, length]]);
+ +

For more information about the constructor syntax and the parameters, see TypedArray.

+ +

Properties

+ +
+
{{jsxref("TypedArray.BYTES_PER_ELEMENT", "Uint16Array.BYTES_PER_ELEMENT")}}
+
Returns a number value of the element size. 2 in the case of an Uint16Array.
+
Uint16Array.length
+
Length property whose value is 3.
+
{{jsxref("TypedArray.name", "Uint16Array.name")}}
+
Returns the string value of the constructor name. In the case of the Uint16Array type: "Uint16Array".
+
{{jsxref("TypedArray.prototype", "Uint16Array.prototype")}}
+
Prototype for the TypedArray objects.
+
+ +

Methods

+ +
+
{{jsxref("TypedArray.from", "Uint16Array.from()")}}

+ +

Uint16Array prototype

+ +

All Uint16Array objects inherit from {{jsxref("TypedArray.prototype", "%TypedArray%.prototype")}}.

+ +

Properties

+ +
+
Uint16Array.prototype.constructor

+
{{jsxref("TypedArray.prototype.buffer", "Uint16Array.prototype.buffer")}} {{readonlyInline}}
+
Returns the {{jsxref("ArrayBuffer")}} referenced by the Uint16Array Fixed at construction time and thus read only.
+
{{jsxref("TypedArray.prototype.byteLength", "Uint16Array.prototype.byteLength")}} {{readonlyInline}}
+
Returns the length (in bytes) of the Uint16Array from the start of its {{jsxref("ArrayBuffer")}}. Fixed at construction time and thus read only.
+
{{jsxref("TypedArray.prototype.byteOffset", "Uint16Array.prototype.byteOffset")}} {{readonlyInline}}
+
Returns the offset (in bytes) of the Uint16Array from the start of its {{jsxref("ArrayBuffer")}}. Fixed at construction time and thus read only.
+
{{jsxref("TypedArray.prototype.length", "Uint16Array.prototype.length")}} {{readonlyInline}}
+
Returns the number of elements hold in the Uint16Array. Fixed at construction time and thus read only.
+
+ +

+
{{jsxref("TypedArray.findIndex", "Uint16Array.prototype.findIndex()")}}
+

+
{{jsxref("TypedArray.forEach", "Uint16Array.prototype.forEach()")}}
+

+
{{jsxref("TypedArray.indexOf", "Uint16Array.prototype.indexOf()")}}
+
Returns the first (least) index of an element within the array equal to the specified value, or -1 if none is found. See also {{jsxref("Array.prototype.indexOf()")}}.
+
{{jsxref("TypedArray.join", "Uint16Array.prototype.join()")}}

+uint16[0] = 42;
+console.log(uint16[0]); // 42
+console.log(uint16.length); // 2
+console.log(uint16.BYTES_PER_ELEMENT); // 2
+
+// From an array
