Processing.js

In my Open Source Development 600 course, I was assigned to work on the bugs 41284 for on Processing.js (tickets 270 -275) which were implementation of simple string functions. I needed to review my javascript which I took in first year and learned the prof. programming style. Here were my code for the first release 0.1.

Convert all characters of a string into a upper case and return the string:

function stringToUpperCase(string str)
{
var strUpperCase = str.touppercase();
return strUpperCase;
}

Or convert all characters of a string to lower case and return the string:

function stringToLowerCase(string str)
{
var strLowerCase = str.tolowercase();
return strLowerCase;
}

To find part of string using substring:


function StringSubstring(string str, int beginIndex, int endIndex)
{
var stringSub;
if(endIndex >0)
stringSub = str.substring(int beginIndex, int endIndex);
else
stringSub = str.substring(int beginIndex)

return stringSub;
}


To find total characters in a string

function strLength(string str){
return str.length();
}


Find a substring within a string and return the first occurrence otherwise return -1

function stringIndexOf(string str, string subStr){
int p1 = str.indexIf(subStr);
if(p1==-1)
return -1;
else
return p1;
}


Get a character in a string at a specific index


function stringCharAt(string str, int strIndex){
if(strIndex > -1 && strIndex < c1 =" str.charAt(strIndex);" href="https://processing-js.lighthouseapp.com/projects/41284/project-workflow">repos and got a public key. Now I need to add my new js file to the branches and test them.
