TypedArray.prototype.with()

The with() method of TypedArray instances is the copying version of using the bracket notation to change the value of a given index. It returns a new typed array with the element at the given index replaced with the given value. This method has the same algorithm as Array.prototype.with().

Syntax

arrayInstance.with(index, value)

Parameters

index: Zero-based index at which to change the typed array, converted to an integer.
value: Any value to be assigned to the given index.

Return value

A new typed array with the element at index replaced with value.

Exceptions

RangeError: Thrown if index >= array.length or index < -array.length.

Description

See Array.prototype.with() for more details. This method is not generic and can only be called on typed array instances.

Examples

Using with()

const arr = new Uint8Array([1, 2, 3, 4, 5]);
console.log(arr.with(2, 6)); // Uint8Array [1, 2, 6, 4, 5]
console.log(arr); // Uint8Array [1, 2, 3, 4, 5]
