What are the differences between typed arrays and regular arrays in JavaScript?

What are the differences between typed arrays and regular arrays in JavaScript?

Typed arrays are array-like objects that provide a mechanism for reading and writing binary data in JavaScript. Unlike regular arrays, which can hold any type of data, typed arrays are designed to hold a specific type of data, such as integers or floats, and have a fixed size.

When should I use typed arrays instead of regular arrays?

You should use typed arrays when you need to handle binary data, such as in WebGL for graphics or when working with large datasets for performance reasons. They offer better performance and memory efficiency for numerical data.

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

Sure! You can create a typed array using the Uint8Array constructor like this: const typedArray = new Uint8Array(10); This creates a typed array of 10 elements, all initialized to 0.

Are there any limitations to using typed arrays?

Yes, typed arrays have some limitations. They can only store a specific type of data, and their size is fixed once created. Additionally, they do not support methods like push or pop that are available in regular arrays.
