What are typed arrays and how do they help with memory management?

Typed arrays are array-like objects that provide a mechanism to read and write raw binary data in memory. They help with memory management by allowing you to work with binary data directly, which can improve performance and reduce memory overhead.

Can you give me an example of how to use typed arrays in JavaScript?

Sure! In JavaScript, you can create a typed array like this: let intArray = new Int32Array(5); This creates an array of 5 integers. You can then set values using intArray[0] = 42;.

What are the benefits of using typed arrays over regular arrays?

Typed arrays offer better performance for numerical computations, as they use a fixed size and type, reducing memory usage and improving speed for operations like rendering graphics or processing large datasets.

Are there any limitations to using typed arrays?

Yes, typed arrays have some limitations, such as being limited to specific data types and not supporting methods like push or pop that are available in regular arrays.
