How can I improve string performance in JavaScript?

How can I improve string performance in JavaScript?

To improve string performance in JavaScript, consider using string concatenation with arrays or using template literals.

What about using the '+' operator for concatenation?

Using the '+' operator is fine for small strings, but for larger strings, it can lead to performance issues due to multiple allocations.

Are there any specific methods or functions I should avoid?

Yes, avoid using 'String.prototype.concat()' for large strings, as it can be less efficient than other methods.

What about using libraries for string manipulation?

Libraries like Lodash can help with string manipulation, but always measure performance to ensure they meet your needs.
