What are the performance differences between JavaScript loops?

What are the performance differences between JavaScript loops?

JavaScript has several types of loops, including for, while, and forEach. Generally, traditional for loops are faster than forEach due to less overhead.

Can you provide a benchmark comparison of these loops?

Sure! In many benchmarks, a simple for loop often outperforms forEach and while loops, especially with large datasets.

What factors affect the performance of these loops?

Factors include the size of the dataset, the complexity of operations within the loop, and the JavaScript engine optimizations.

Is there a specific scenario where forEach is better?

Yes, forEach can be more readable and easier to use for operations on arrays, especially when dealing with callbacks.
