TypedArray.BYTESPERELEMENT

## Value

A number whose value depends on the type of `TypedArray`.

{{js_property_attributes(0, 0, 0)}}

## Description

`TypedArray` objects differ from each other in the number of bytes per element and in the way the bytes are interpreted. The `BYTES_PER_ELEMENT` constant contains the number of bytes each element in the given `TypedArray` has.

The `BYTES_PER_ELEMENT` property is both an _instance property_ and a _static property_. It's available on both `TypedArray` subclass constructors and on instances of those constructors.

As an instance property, `BYTES_PER_ELEMENT` is defined on the constructor's `prototype`.

```js
console.log(Object.hasOwn(Int8Array.prototype, "BYTES_PER_ELEMENT")); // true

Int8Array.BYTES_PER_ELEMENT; // 1
Uint8Array.BYTES_PER_ELEMENT; // 1
Uint8ClampedArray.BYTES_PER_ELEMENT; // 1
Int16Array.BYTES_PER_ELEMENT; // 2
Uint16Array.BYTES_PER_ELEMENT; // 2
Float16Array.BYTES_PER_ELEMENT; // 2
Int32Array.BYTES_PER_ELEMENT; // 4
Uint32Array.BYTES_PER_ELEMENT; // 4
Float32Array.BYTES_PER_ELEMENT; // 4
Float64Array.BYTES_PER_ELEMENT; // 8
BigInt64Array.BYTES_PER_ELEMENT; // 8
BigUint64Array.BYTES_PER_ELEMENT; // 8
