How to optimize JavaScript loops?

Asked by Jeremy46231 on 2025-09-01

I'm working with large datasets in JavaScript and need to optimize for loop performance. Which techniques yield the best results?

Answers

Use for...of loops instead of traditional for, avoid nested loops where possible, and cache length properties when iterating arrays.

Sometimes Array.prototype.forEach() is more readable than traditional loops.
