Due to JavaScript’s asynchronous nature, anonymous functions are integral and are used much more often than in other languages. An anonymous function that is a nameless function that is created on the fly, and often used as the argument to another function to be run later as a callback function. Named Function VS Anonymous Function in JavaScript 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. Guide to Javascript Anonymous Function. Here we discuss the syntax and working of Javascript Anonymous Function along with examples and code implementation. Introduction to JavaScript anonymous functions An anonymous function is a function without a name. An anonymous function is often not accessible after its initial creation. The following shows an anonymous function that displays a message: 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. 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. 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. In JavaScript, an anonymous function is that type of function that has no name or we can say which is without any name. When we create an anonymous function, it is declared without any identifier. It is the difference between a normal function and an anonymous function. What is an anonymous function in JavaScript? Javascript Front End Technology Object Oriented Programming A function expression is similar to and has the same syntax as a function declaration One can define "named" function expressions (where the name of the expression might be used in the call stack for example) or "anonymous" function expressions.
