Javascript TypedArray

In JavaScript, a TypedArray is a type of object that provides a way to work with binary data in a specific format.

TypedArrays are part of the ArrayBuffer object, and they offer a structured way to deal with raw binary data.

There are several types of TypedArrays, each corresponding to a specific data type and format.

Here are some commonly used TypedArrays:

Int8Array, Uint8Array, Int16Array, Uint16Array, Int32Array, Uint32Array, Float32Array, Float64Array:

These represent arrays of 8-bit, 16-bit, 32-bit signed and unsigned integers, as well as 32-bit and 64-bit floating-point numbers.

BigInt64Array, BigUint64Array:

These are for working with 64-bit signed and unsigned integers.

Creating TypedArrays:

Ways we can create TypedArrays:

Using ArrayBuffers:

// Creating an ArrayBuffer
let buffer = new ArrayBuffer(16);

// Creating a TypedArray using the ArrayBuffer
let int32Array = new Int32Array(buffer);

Directly from Arrays or Other TypedArrays:

let intArray = new Int32Array([1, 2, 3, 4, 5, 6, 7, 8, 9]);

let floatArray = new Float32Array(intArray);

Accessing and Modifying Elements:

TypedArrays provide a way to read and write binary data at a specific position.

Example:

let intArray = new Int32Array([20, 40, 60, 80, 100, 120, 140]);

console.log(intArray[3]); // 80

intArray[4] = 85;
console.log(intArray); // Int32Array [20, 40, 60, 80, 85, 120, 140]

Note:

TypedArrays are commonly used in scenarios where direct manipulation of binary data is required, such as working with network protocols, file I/O, or WebGL.

They provide a more efficient and reliable way to handle binary data compared to traditional JavaScript arrays.
