How do I create typed arrays in JavaScript?

You can create typed arrays in JavaScript using the TypedArray constructors like Int8Array, Uint8Array, etc. For example, let arr = new Int16Array(5); creates a typed array of 5 elements.

What are the different types of typed arrays available?

JavaScript provides several typed arrays: Int8Array, Uint8Array, Float32Array, Float64Array, and more. Each serves different purposes based on the data type.

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

Sure! Here's a simple example:

let floatArray = new Float32Array(3);
floatArray[0] = 1.1;
floatArray[1] = 2.2;
floatArray[2] = 3.3;
console.log(floatArray);

This creates a Float32Array and assigns values to it.

How do typed arrays differ from regular arrays?

Typed arrays are more efficient for numerical data and provide a fixed size, while regular arrays can hold mixed types and are dynamically sized.
