What are the differences between string template literals and concatenation in JavaScript?

What are the differences between string template literals and concatenation in JavaScript?

String template literals allow for easier string interpolation and multi-line strings, while concatenation uses the '+' operator.

Can you give me an example of both?

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

Which one is more efficient?

Template literals are generally more readable and easier to maintain, but performance differences are usually negligible.

Are there any limitations to using template literals?

Template literals can't be used in certain contexts like object keys, but they are very versatile otherwise.
