Parameters II

If we can set one parameter, can we set two?

We can set as many parameters as we'd like by adding them when we declare the function, separated by commas, like this:

function getRemainder(numberOne, numberTwo) { console.log(numberOne % numberTwo); } getRemainder(365, 27); // Output: 14
  1. The getRemainder function has two parameters: numberOne and numberTwo.
  2. When we call the getRemainder function on the last line, we include two numbers as the parameters, also separated by commas. This is referred to as passing in parameters to a function.

    In this case, we are telling the function to assign numberOne the value of 365 and numberTwo the value of 27. We are passing in 365 and 27 to the getRemainder function.

  3. When the getRemainder runs, the function knows what numberOne and numberTwo equal since we passed in two parameters when we called the function. Therefore it evaluates 365 % 27, which produces the result 14.

By adding multiple parameters, we can build functions that are more flexible. Now the function has two variables that we can define when we call the function.
