What is the performance of the for...of loop in JavaScript?

What is the performance of the for...of loop in JavaScript?

The for...of loop is generally slower than traditional for loops and forEach, especially for large arrays.

Why is it slower? Can you explain the reasons?

It involves more overhead due to its iterator protocol, which can add extra function calls compared to indexed loops.

Are there scenarios where for...of is preferred despite its performance?

Yes, for...of is preferred for its readability and ease of use, especially when working with iterable objects.

What about the performance of forEach compared to for...of?

forEach is also slower than a traditional for loop, but it can be more readable than for...of in some cases.
