What are the performance benchmarks for typed arrays in JavaScript?

Typed arrays in JavaScript provide a way to work with binary data efficiently. They are designed for high-performance scenarios, especially when dealing with large datasets. Benchmarks show that typed arrays can significantly outperform regular arrays in terms of speed and memory usage.

Can you give me some specific examples of benchmarks?

Sure! For instance, operations like reading and writing data to typed arrays can be up to 10 times faster than regular arrays. Additionally, when performing mathematical operations on large datasets, typed arrays can reduce processing time significantly.

What types of typed arrays are there?

JavaScript offers several types of typed arrays, including Int8Array, Uint8Array, Float32Array, and more. Each type is designed for specific data types and provides different ranges and precision.

Are there any downsides to using typed arrays?

Yes, while typed arrays are efficient, they have some limitations. For example, they can only store a specific type of data, and they require a fixed size, which can lead to memory issues if not managed properly.
