An anonymous function is a function without a name! Anonymous functions are commonly assigned to a variable name or used as a callback function. The syntax would be as below,
javascript
1function (optionalParameters) {
2 //do something
3 }
4
5const myFunction = function(){ //Anonymous function assigned to a variable
6 //do something
7};
8
9[1, 2, 3].map(function(element){ //Anonymous function used as a callback function
10 //do something
11});Let's see the above anonymous function in an example,
javascript
1var x = function (a, b) {
2 return a * b;
3 };
4
5var z = x(5, 10);
6
7console.log(z); // 50Advertisement
