What are typed arrays and how do I use them in JavaScript?

Typed arrays are array-like objects that provide a mechanism for reading and writing binary data in JavaScript. They are useful for handling raw binary data, such as images or audio.

Can you give me an example of how to create a typed array?

Sure! You can create a typed array using the Uint8Array constructor. For example: let arr = new Uint8Array(10); This creates a typed array of 10 elements, all initialized to 0.

How do I fill a typed array with values?

You can fill a typed array using the set method. For example: arr.set([1, 2, 3]); This will fill the first three elements of the array with the values 1, 2, and 3.

What are the benefits of using typed arrays?

Typed arrays provide better performance for numerical computations and allow you to work with binary data more efficiently compared to regular arrays.
