// This is your function. It is waiting in memory to be called so it can be executed/run.
function warning() { 
  alert('Warning, warning, warning!'); 

// This is how you call a function:

Let's take the function call apart: warning();
+ warning is the name of the function. You have to tell javaScript which function you want to call.
+ () is an operator. This () operator is a function itself under the hood which does all the work of  finding the function in memory and getting the function to execute it's coding.
+ ; is the semi-colon. Always use a semi-colon at the end to let javaScript know you are done with your statement. It is considered best coding practice.

Hi, you can call the function just by typing it out:


You can leave the brackets empty in this case.

The answer is:


Leave out the semi-colon because that is already at the end of the line that you write in, other wise you would add that.

Hi mhammad hamza. The answer is in your question; your function name is 'warning' so start with that: 'warning.call();' This is the method to call a function. Good luck.
