How do I define an anonymous function in JavaScript?

You can define an anonymous function by simply creating a function without a name. For example: const myFunction = function() { console.log('Hello!'); };

Can you show me how to call that function?

Sure! You can call the function by using its variable name followed by parentheses: myFunction(); This will output 'Hello!'.

What are the benefits of using anonymous functions?

Anonymous functions are useful for creating functions on the fly, especially as arguments to other functions, like in callbacks.

Are there any downsides to using them?

One downside is that they can't be reused easily since they don't have a name. This can make debugging harder.
