What are the performance differences between for and forEach in JavaScript?

What are the performance differences between for and forEach in JavaScript?

The 'for' loop is generally faster than 'forEach' because it has less overhead. 'forEach' is more readable but can be slower.

Can you explain why 'for' is faster?

Sure! The 'for' loop has a simpler structure and doesn't create a function context for each iteration, reducing overhead.

Are there any scenarios where 'forEach' is preferred?

Yes, 'forEach' is preferred for its readability and when you need to work with array methods like chaining.

What about performance in large arrays?

In large arrays, the performance difference becomes more noticeable, so using 'for' can be beneficial for speed.

Is there a way to measure the performance of both?

Yes, you can use the console.time() and console.timeEnd() methods to measure the execution time of both loops.
