Its anonymous because there is no name assigned to it. The function can have parameters passed in, as we will see in a moment, just like any other function. Inside the function is the actual code you want to execute. After the function definition is another set of parenthesis. This last pair of causes the function to execute as soon as it is When a function is defined without a name, it's known as an anonymous function. The function is stored in memory, but the runtime doesn't automatically create a reference to it for you. At first glance, it may appear as if such a thing would have no use, but there are several scenarios where anonymous functions are very convenient. An anonymous function allows a programmer to create a function that has no name. In other words anonymous functions can be used to store a bit of functionality in a variable and pass that piece of functionality around it and created at runtime. Anonymous functions are declared using the function operator instead of the function declaration. An anonymous function is, as its name implies, a function without a name (no pun intended). They are most popularly used to define function expressions. An example of such usage is shown below. In conclusion, an anonymous function is a function that is not stored but is associated with a variable. Anonymous functions can accept inputs and return outputs, just as standard functions Anonymous functions can accept inputs and return outputs, just as standard functions The function above is actually an anonymous function (a function without a name). Functions stored in variables do not need function names. They are always invoked (called) using the variable name. The function above ends with a semicolon because it is a part of an executable statement. Anonymous Functions - In computer programming, an anonymous function (function literal, lambda abstraction, or lambda expression) is a function definition that is not bound to an identifier. Anonymous functions are often [1] arguments being passed to higher-order functions , or used for constructing the result of a higher-order function that needs to return a function. Summary: in this tutorial, you will learn about JavaScript anonymous functions. Introduction to JavaScript anonymous functions. An anonymous function is a function without a name.
