What are anonymous functions?

Anonymous functions, also known as lambda functions, are functions without a name that can be defined on-the-fly in programming languages. They are often used for one-off tasks or in situations where a named function is not necessary.

Anonymous functions are commonly used in languages like JavaScript, Python, and PHP for tasks that require a small, simple function to be passed as an argument to another function or assigned to a variable. They make the code more concise and readable by defining the function inline where it is needed.

Benefits of using anonymous functions:

• Concise code: They allow you to write functions in a more compact way.
• No need for a name: Instead of defining a named function, you can create an anonymous function directly where it is needed.
• Flexibility: They can be used dynamically without having to define them beforehand.

In conclusion, anonymous functions are a powerful tool in programming that offer flexibility and simplicity when dealing with functions that are short-lived or don't require a formal name.
