Instead of using console.log to print our output, functions can also return their result into a variable. This enables us to write a function that performs a task and then saves the result as a variable that we can use elsewhere.

For example:

var timesFive = function (number) { return number * 5; }; console.log(timesFive(3)); // Output: 15
  1. Instead of writing function timesFive(){}, we declared a variable named timesFive, and set it equal to a function with no name. This is called an anonymous function.
  2. Inside the function, we used the keyword return, which will return the result of number * 5 into the timesFive variable.
  3. On the last line, we called timesFive(3), which invoked the timesFive function, multiplied 5 times 3, and returned the result of 15, which was then logged to the console.
