Final answer:
Anonymous functions are used when you only need the function temporarily and do not plan on using it elsewhere in your code, while named functions are used when you need to reuse the function or when you want to make your code more readable and organized.
Step-by-step explanation:
An anonymous function is a function that is defined without a name. It is usually used when you only need the function temporarily and do not plan on using it elsewhere in your code. One common use of anonymous functions is in event handling, where you want to assign a function to an event without cluttering your code with lots of named functions. For example, in JavaScript, you can define an anonymous function to handle a click event:
document.getElementById('myButton').addEventListener('click', function() {
alert('Button clicked!');
});
In contrast, a named function is a function that is assigned a name and can be called multiple times from different parts of your code. You would use a named function when you need to reuse the function or when you want to make your code more readable and organized. For example, you could define a named function to calculate the square of a number:
function square(number) {
return number * number;
}
