Which is better for or foreach in javascript?..

Answer / Sandeep Anand

In JavaScript, both 'for' loops and 'forEach' methods can be used to iterate over arrays. The choice between them depends on the specific use case. For simple cases where you just need to loop through an array once and don't need to break early or update the array, forEach is more concise. However, if you need control over the iteration (e.g., breaking early or updating the array), use a 'for' loop.
