What code is this?

[chrisburton]

Anyone have any idea what code this entails? http://www.stanford.edu/class/cs101/code-1-exercises.html

I thought it was Javascript but after testing, something entirely different happens (e.g. print() brings up the printer settings).

Looks like Python… save for the semicolons.

I hit the backlink at the top of the page and it seems to be a javascript course.

EDIT –

Aha

Note “print” is not a normal part of Javascript, I added it for CS101

@Paulie_D Where do you see that quote?

I find it completely stupid to teach print();as if it actually does what it shows when it actuality, it doesn’t. It’s just confusing. After briefly reading through some docs it states that print(); is a function so that is why it’s acting comparable to document.write();.

I hit the backlink and then selected the introduction link.

When he first demos ‘print’ in the first code example, it’s the last comment in the green boxed”notes”.

Gotcha. Thanks.

Well, it does do what it shows. It’s just not a native JS function: it’s a user-defined function.

Here’s it’s definition, if you’re interested:

// Print any number of things, separated by spaces and ending with a carriage return.
function print() {
  // printlimit feature
  if (window.globalPrintCount <= 0) {
    if (window.globalPrintCount == 0) {
      printOne("***print output limited***");
      printOne("<br>");
      window.globalPrintCount--;
    }
    return;
  }
  window.globalPrintCount--;
    

 for (var i=0; i<arguments.length; i++) {
   printOne(arguments[i]);
 }
 printOne("<br>");
}

[JavaScript] syntax is strict and narrow

LOL

What I mean is that print() seems to already be native to JS (from my testing it opens printer settings) so creating a user-defined function to change that seems kind of stupid to teach because it can be confusing.

Ha! Was not aware of that. Upon research, it seems it’s not part of any spec, but is supported basically everywhere. Given this, yes, I agree that creating a UDF named print is “kind of stupid.”
