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=1,b=0){
if(a>b)
return a;


}
max(3,2);

Youre on the right step, but there are a couple syntax errors in there. You dont have to initialize the arguments you are expecting to be passed it, so

 function max(a=1, b=2 )

can just be 

function max(a,b)

Also you dont have to call your function at the end. The challenge has their own test cases that will call your function. Lastly it would be a good idea to give a body to your if statement and it also needs an else. What would happen if b > a nothing would be returned
