TypedArray.prototype.reverse()
BaselineWidely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2016.
Thereverse() method ofTypedArray instances reverses a typed arrayin place and returns the reference to the same typed array, the first typed array element now becoming the last, and the last typed array element becoming the first. In other words, elements order in the typed array will be turned towards the direction opposite to that previously stated. This method has the same algorithm asArray.prototype.reverse().
Try it
const uint8 = new Uint8Array([1, 2, 3]);uint8.reverse();console.log(uint8);// Expected output: Uint8Array [3, 2, 1]Syntax
reverse()Parameters
None.
Return value
The reference to the original typed array, now reversed. Note that the typed array is reversedin place, and no copy is made.
Description
SeeArray.prototype.reverse() for more details. This method is not generic and can only be called on typed array instances.
Examples
Using reverse()
const uint8 = new Uint8Array([1, 2, 3]);uint8.reverse();console.log(uint8); // Uint8Array [3, 2, 1]Specifications
