How can I improve string performance in JavaScript?

To improve string performance in JavaScript, consider using string builders or arrays for concatenation.

What are string builders and how do they work?

String builders are objects that allow you to build strings efficiently by appending to an array and then joining.

Are there any specific methods I should avoid for string manipulation?

Yes, avoid using the '+' operator for concatenation in loops, as it can lead to performance issues.

What about using template literals?

Template literals are generally efficient and improve readability, but for large concatenations, consider using arrays.
