Create a Max() Function

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.

I have been stuck on this for awhile. I keep getting a parse error. I tried using the parseInt and I keep getting the same error. How do I correct it?

script.js 
function max ( big, little){
  var equality =  parseInt(big * little);
  return equality; 
}

  if max parseInt(2, 1){
      "correct";
  } else max parseInt(2, 1){
    "incorrect";
 }

function max ( ){


    if max (big, little){


     big > little;
      return big;


  } else max (big, little){


      big < little;



return little;


 }

}

  max(2, 1);```

You almost have the formatting down. The 3 backticks need to be on thier own lines, but the first one can have "js" after for syntax coloring.

I'll repeat the things that vanished a few minutes ago:

  • the parameters must be named in the function declaration (top line)
  • the function name will not be part of the conditional
  • the comparison expression should go inside the parentheses after the "if"
  • the "else" doesn't use any expression, it handles the "left over" cases automatically

You won't need to use parseInt for this challenge, it's only for converting strings into numbers. You can assume both of the arguments given will be numbers already..

Other things to keep in mind:

  • the conditional statement should be inside the function
  • the function will always return one of the arguments passed in (the largest one)
  • you won't need any variables other than the parameters

Did you implement the other hints as well? If you still have issues, remember to update the question to show what the code looks like now after the changes.
