TypedArray.prototype.reverse()

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 reverse() method of TypedArray instances reverses a typed array in 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 as Array.prototype.reverse().

Try it

const uint8 = new Uint8Array([1, 2, 3]);
uint8.reverse();

console.log(uint8);
// Expected output: Uint8Array [3, 2, 1]

js
const uint8 = new Uint8Array([1, 2, 3]);
uint8.reverse();

console.log(uint8); // Uint8Array [3, 2, 1]
