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().
const uint8 = new Uint8Array([10, 20, 30, 40, 50]);
const uint8String = uint8.toString();
console.log(uint8String.startsWith("10"));
// Expected output: true
toString()
None.
A string representing the elements of the typed array.
See Array.prototype.toString() for more details. This method is not generic and can only be called on typed array instances.
const uint8 = new Uint8Array([1, 2, 3]);
// Explicit conversion
console.log(uint8.toString()); // 1,2,3
// Implicit conversion
console.log(`${uint8}`); // 1,2,3
