How can I use the spread operator with strings in JavaScript?

How can I use the spread operator with strings in JavaScript?

You can use the spread operator to convert a string into an array of characters. For example, const chars = [...'hello']; results in ['h', 'e', 'l', 'l', 'o'].

Can I use it to join strings together?

Yes! You can spread multiple strings into an array and then join them. For example, const result = [...'Hello', ...'World'].join(' '); gives you 'Hello World'.

What about using it with template literals?

You can combine the spread operator with template literals. For instance, const str = ${[...'Hello', ...'World'].join(' ')}; results in 'Hello World'.

Are there any performance considerations?

Using the spread operator is generally efficient, but for very large strings, consider performance impacts and memory usage.
