Bug in Lterm Project (Fixed)

Lterm is a NJACK Winter of Code project. NWoC is a program that helps students understand the paradigm of Open Source contribution and gives them real world software development experience.
Now, something about the project :- Its a Terminal like copy but for Website, Pretty neat eh ?


At first i checked the project it was pretty cool so i tried more commands, as you can see after you execute every command and press help it shows completed and not completed , probably an array of all the items with a [0,1] value for not completed and completed.

Everything worked great but, When i executed the clear command which didnt show "completed" after i execute it. it was a BUG . i forked the project and went into the codebase :-

• Reading the development section of documentation i knew i had to check the js/main.js
  
• i knew they would be having an array arr for checking if the command is executed or not, initially the value was 0.
  
• They changed the value to 1 on every execution like this :- arr[6]=1;
  
• they had a correct implementation of "clear" command which works with "Clear" aswell.
  
  Then, Why didn't it worked ? i thought about it a bit, then saw that they didnt had implemented the functionality of "clear" command but somehow it worked when i executed, that means there must be some other file which is doing all the ground work. Soon enough i checked the index.html and checked all the linked js files
  
  There was this file terminal.min.js which was interesting, i looked into it and searched "clear:function(){" and got the root of the problem :D
  
  Then, i added the arr[9]=1; but it still didnt worked like i wanted.. hmm what could be the problem this time ?
  
  Maybe the file is not able to access arr ? But it's declared var arr It should be global, i searched on StackOverflow and found an alternative, window.arr could also make a variable globally accessible. Hmm let's try it in the main.js file
  
  And Violla executing the clear or Clear command works just as it should be.
