TypedArray.prototype.toString()
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2017.
The toString() method of TypedArray instances returns a string representing the specified typed array and its elements. This method has the same algorithm as Array.prototype.toString().
Try it
const uint8 = new Uint8Array([10, 20, 30, 40, 50]);
const uint8String = uint8.toString();
console.log(uint8String.startsWith("10"));
// Expected output: true
Syntax
js

Parameters

Return value
A string representing the elements of the typed array.
Description

Examples
Converting a typed array to a string
js
const uint8 = new Uint8Array([1, 2, 3]);

// Implicit conversion
