In JavaScript, functions are first-class citizens, meaning they can be treated as values and passed around like any other variable. One of the key concepts related to this is anonymous functions. In this article, we’ll explore what anonymous functions are, how they work, and how they can be created using both the traditional function syntax and the modern arrow function syntax.

What are Anonymous Functions?

An anonymous function is simply a function that does not have a name. Unlike named functions, which are declared with a name for easy reference, anonymous functions are usually created for specific tasks and are often assigned to variables or used as arguments for other functions.

In JavaScript, you normally use the function keyword followed by a name to declare a function. However, in an anonymous function, the name is omitted. These functions are often used in situations where you don’t need to reuse the function outside its immediate context.
