Can I have functions within functions?

Yes, functions can be nested within other functions. This is known as function nesting or closure.

How do I ensure my function works across different browsers?

Stick to using modern JavaScript features, and consider using a transpiler like Babel to ensure compatibility with older browsers.

What’s the difference between function and arrow => notation?

Arrow functions offer a concise syntax and automatically inherit the context from their containing function, making them useful for certain scenarios. Traditional function notation is still widely used and provides more flexibility in terms of context binding.

How do I return multiple values from a function?

You can return multiple values by returning an object or an array containing the values you need.

Should I prioritize code efficiency or readability when writing functions?

Both efficiency and readability are important. Write clear and understandable code first, and then optimize for performance if necessary.
