TypedArray.prototype.entries() - JavaScript | MDN

TypedArray.prototype.entries()

Baseline Widely available

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

Try it
const uint8 = new Uint8Array([10, 20, 30, 40, 50]);
const eArr = uint8.entries();

eArr.next();
eArr.next();

console.log(eArr.next().value);
// Expected output: Array [2, 30]
Syntax Parameters

None.

Return value

A new iterable iterator object.

Description

See Array.prototype.entries() for more details. This method is not generic and can only be called on typed array instances.

Examples Iteration using for...of loop
const array = new Uint8Array([10, 20, 30, 40, 50]);
const arrayEntries = arr.entries();
for (const element of arrayEntries) {
  console.log(element);
}
Alternative iteration
const array = new Uint8Array([10, 20, 30, 40, 50]);
const arrayEntries = arr.entries();

console.log(arrayEntries.next().value); // [0, 10]
console.log(arrayEntries.next().value); // [1, 20]
console.log(arrayEntries.next().value); // [2, 30]
console.log(arrayEntries.next().value); // [3, 40]
console.log(arrayEntries.next().value); // [4, 50]
