How do I use typed arrays in JavaScript?

Typed arrays are array-like objects that provide a mechanism for reading and writing raw binary data in JavaScript. You can create a typed array using constructors like Uint8Array, Float32Array, etc.

Can you give me an example of creating a typed array?

Sure! You can create a Uint8Array like this: let arr = new Uint8Array(5); This creates an array of 5 elements, all initialized to 0.

How do I fill this typed array with values?

You can fill it using a loop or the set method. For example: arr.set([1, 2, 3, 4, 5]); will fill the array with those values.

What are the benefits of using typed arrays?

Typed arrays provide better performance for numerical computations and allow you to work with binary data directly, which is useful for tasks like WebGL or audio processing.
