I wish this helpful for you If you want output as string you don't need to Split. Just get the LastIndexOf the , character and perform Substring on the variable:
code :
var a = "77,82,83";
var newString = a.Substring(0, a.LastIndexOf(',')); // 77,82
var a = "77,82,83";
var lastIndex = a.LastIndexOf(',');

if (lastIndex > 0)
    var newString = a.Substring(0, lastIndex);
a = string.Join(",", a.Split(',').Where(i => i != "83"));

I hope this helps . To remove the ", " part which is immediately followed by end of string, you can do:
code :
str = str.replaceAll(", $", "");
String str = "kushalhs, mayurvm, narendrabz, ";
str = str.replaceAll(", $", "");
System.out.println(str);  // prints "kushalhs, mayurvm, narendrabz"

it helps some times if 12.1 that should be replaced as blank is the only word in that string you can use this:
code :
stringValue= stringValue.replaceAll("^12\\.1$","blank").replaceAll("12\\.1,","");

How create array from comma separated string, sort it low to high, then join it back into comma separated string?

With these it helps The first step is splitting the string in specified places, in your case - comma ,. Then use simple sort function and then you just have to join it, again with the comma sign.
code :
var orders = '1115672,1115676,1115677,1115682,1115684';

console.log(orders.split(',').sort((a,b) => a-b).join(','));
