Javascript Basics, alert numbers

Not sure what this one needs?

Call the function and display the results in an alert dialog. You can pass the results of a function directly to the alert() method. For example, to display the results of the Math.random() method in an alert dialog you could type this:

function max(num1, num2) { if (num1 > num2) { return num1; } else { return num2; } }

alert(max(num1, num2));

Last question on the course for me to complete Javascript basics woo

You have to create a function and call it.

Remember the syntax of a function:

functionName(parameter1, parameter2, parameter3) { code to be executed }

Just create a random function, let's say:

function random(value1, value2) { return value1 + value2; }

//And call it by using the build in alert(); function

alert(random(4,3));

//And you'll get 7 shown in an alert box.

With the previous part of the challenge, you created a max function. Now, you just need to call it in an alert. You will need to pass 2 numbers to your max function.

If anyone needs this answered I must share my findings due to being stuck on it for a while, see below; ( I found that the only way that it worked for me was closing parentheses which I overlooked, all three must be closed for this to work) hope this helps anyone not picking up on this minor oversight:

alert( Math.random( ) ); function max( num1, num2 ) { if (num1>num2) { return num1; } else { return num2; } } alert( Math.random(max(1, 2)) );
