What are the differences between string templates and concatenation in JavaScript?

What are the differences between string templates and concatenation in JavaScript?

String templates (template literals) allow for easier multi-line strings and variable interpolation using backticks (`). Concatenation uses the plus sign (+) to combine strings.

Can you give me an example of both?

Sure! For concatenation: let greeting = 'Hello, ' + name + '!'; For string templates: let greeting = Hello, ${name}!;.

Which one is more efficient?

In terms of performance, string templates are generally more efficient for complex strings, but for simple cases, the difference is negligible.

Are there any limitations to using string templates?

Yes, string templates cannot be used in older browsers that do not support ES6. Also, they can be less readable for very complex expressions.
