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

The spread operator allows you to expand elements of an iterable, like a string, into individual characters. For example, you can use it like this: const str = 'hello'; const chars = [...str]; This will create an array `['h', 'e', 'l', 'l', 'o']'.

Can I use it to combine two strings?

Yes! You can combine strings using the spread operator. For example: const str1 = 'Hello'; const str2 = 'World'; const combined = [...str1, ' ', ...str2].join(''); This will give you 'Hello World'.

What about using it in a function?

You can definitely use the spread operator in functions. For instance, if you want to create a function that takes multiple strings and combines them, you can do: function combineStrings(...strings) { return strings.join(' '); }.

Are there any performance considerations?

Using the spread operator is generally efficient for small strings, but for very large strings, consider performance implications as it creates new arrays.
