JavaScript JavaScript Basics (Retired) Creating Reusable Code with Functions Create a max() Function

there is a syntax error in my code, any idea how to fix it thanks!

Here is the question:

Create a new function named max which accepts two numbers as arguments (you can name the arguments, whatever you would like). The function should return the larger of the two numbers.

HINT: You'll need to use a conditional statement to test the 2 parameters to see which is the larger of the two.

script.js 
function max(a,b){
  if (a>b) {
    return (a);
  }
}
max（10,8）;

Sorry Eddie, I misread the problem.

Right now your conditional statement isn't working. It doesn't know what to do if a is not greater than b.

Try writing an if else statement

Also, make sure that the conditional statement is working before you call the function.

get rid of the spaces when you are calling the max function should be: max(10,8);

Hey Eddie,

Try moving your parameters right next to the function. max(10, 8);

I ran your code through jshint (http://jshint.com/) and it didn't like your parenthesis. JavaScript can be picky like that.
