The join() method of TypedArray instances creates and returns a new string by concatenating all of the elements in this typed array, separated by commas or a specified separator string. If the typed array has only one item, then that item will be returned without using the separator. This method has the same algorithm as Array.prototype.join().
const uint8 = new Uint8Array([10, 20, 30, 40, 50]);
console.log(uint8.join());
// Expected output: "10,20,30,40,50"
console.log(uint8.join(""));
// Expected output: "1020304050"
console.log(uint8.join("-"));
// Expected output: "10-20-30-40-50"
separator Optional
A string to separate each pair of adjacent elements of the typed array. If omitted, the typed array elements are separated with a comma (",").
A string with all typed array elements joined. If array.length is 0, the empty string is returned.
See Array.prototype.join() for more details. This method is not generic and can only be called on typed array instances.
const uint8 = new Uint8Array([1, 2, 3]);
uint8.join(); // '1,2,3'
uint8.join(" / "); // '1 / 2 / 3'
uint8.join(""); // '123'
