I am a bit confused about where to go on this one. In particular the format I need for the conditionals

Any help appreciated!

script.js 
function max(height, length)
if (height > length) {
  return height
} else (length > height) {
  return length
}

Hi Justin,

You need the function to return either the 'height' if larger or the 'length'. So you would need an 'if then else'. If the height is not greater than the length, then the length should be returned.

function max(height, length) {
  if (height > length) {
    return height
  } else {
    return length
  }
}

If you wanted to check multiple , the correct syntax is below, but it is good practice to return a default if something is expected to be returned. You can chain together as many as you like, but if you have that many, then maybe a 'switch' statement would work better, but that may be in another lesson.

function check(a,b,c) {
  if (a > b) {
    return "a is greater than b";
  } else if (a > c) {
    return "a is greater than c but not b";
  } else {
    return "a is neither greater than b or c!";
  }
}
