TypedArray.prototype.entries()

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

js
entries()

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

undefined

Iteration using for...of loop

js
const array = new Uint8Array([10, 20, 30, 40, 50]);
const arrayEntries = arr.entries();
for (const element of arrayEntries) {
  console.log(element);
}

Alternative iteration

js
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]
