The keys()
method of TypedArray
instances returns a new array iterator object that contains the keys for each index in the typed array. This method has the same algorithm as Array.prototype.keys()
.

None.
A new iterable iterator object.
See Array.prototype.keys()
for more details. This method is not generic and can only be called on typed array instances.
const arr = new Uint8Array([10, 20, 30, 40, 50]); const arrKeys = arr.keys(); for (const n of arrKeys) { console.log(n); }
const arr = new Uint8Array([10, 20, 30, 40, 50]); const arrKeys = arr.keys(); console.log(arrKeys.next().value); // 0 console.log(arrKeys.next().value); // 1 console.log(arrKeys.next().value); // 2 console.log(arrKeys.next().value); // 3 console.log(arrKeys.next().value); // 4
