Explanation: This can't be null in C# virtual instance methods - I was so confused by the widespread use of this check that I asked this question at SO: https://stackoverflow.com/questions/31747718/can-this-be-null-in-c-sharp-virtual-methods-what-happens-with-the-rest-of-ins

String.prototype.followCase=function(b){
if(b==b.toUpperCase()){return this.toUpperCase();}
if(b==b.toLowerCase()){return this.toLowerCase();}
if(b==b.capitalize()){return this.capitalize();}
return this;
};
String.prototype.atRemoveAdd=function(index,n,string){
return this.substring(0,index)+string+this.substring(index+n,this.length);
};
String.prototype.matchIndex=function(re){
var a=[];
while((match=re.exec(this))!==null){
a.push({chars:match[0].length,index:match.index});
}
return a;
};
String.prototype.caseReplace=function(o,n){
for(var s=this,a=this.matchIndex(o),shift=0,i=0;i<a.length;i++){
var c=n.followCase(this.substring(a[i].index,a[i].index+a[i].chars));
s=s.atRemoveAdd(a[i].index+shift,a[i].chars,c);
shift+=c.length-a[i].chars;
}
return s;
};My code from 2016 for the hall of shame where I realized today that caseReplace could just return this.replace(o,m=>n.followCase(m)) instead.

final int two_fifty_five_hex = 0xFF
final int two_fifty_five_dec = 255
One is in hex but the other is in decimal! Watch out, make sure you use the correct 255, not the other 255.

if(typeof(sortOrder) != "boolean"){

filtered.sort(function (a, b) {
if(sortOrder == true){
return (CustomOrder(a.status) > CustomOrder(b.status) ? 1 : -1);
}
else if(sortOrder == false){
return (CustomOrder(a.status) < CustomOrder(b.status) ? 1 : -1);
}
});The status property is a string ("Started", "Running", "Failed", "Finished", etc.), and CustomOrder is a function with a switch that just returns a predefined integer for each string. I switched CustomOrder to just be a simple lookup table object, and the sort call was changed to filtered.sort((a, b) => CustomOrder[a.status] - CustomOrder[b.status]);
