Home > JavaScript Questions > How to define an anonymous function?
An anonymous function can be defined in a similar way as a normal function but it would not have any name.
Example
//Example 1
function bob() {
...
}
bob();
//Example 2
var bob = function(){
...
};
bob();
Example 1 creates a function with name "bob". Additionally, a variable named "bob" is created in the current scope and is assigned to the function.
Example 2 declares an unnamed function and assigns it to a new variable named "bob".
We can see that these two ways of defining a function are essentially the same - both result in a function being created, and a new variable named "bob" assigned to the current scope. However, the second function is anonymous.
