Merge two list together side-by-side RANDOM-ized

Hi folks, I was asked how to
random the two list together side-by-side.

```
//EmEditor Script (JavaScript)
// Merge two list together side-by-side RANDOM-ized
// shuffle intermix stochastic stochastically
// (see examples) Writes result to new document.

//=======================================================
//============ U S E R S E T T I N G S ==================

// Separate your two input list by at least 5 #'s
// Example input:
//  JAMES
//  JOHN   <<< Left side in output
//  WILLIAM
//  RICHARD
//  CHARLES
//  ##########  <<< Five or more #'s, but not less!
//  MARY
//  PATRICIA
//  LINDA  <<< Right side in output
//  BARBARA
//  ELIZABETH
Separator = "#####";

// Delimiter to be used for separating
// consecutive values on a single line.
// Join both input lists side-by-side,
// Example output:
//  WILLIAM + ELIZABETH
//  CHARLES + PATRICIA
//  RICHARD + BARBARA
//  JAMES + MARY
//  JOHN + LINDA
//  or
//  JOHN + BARBARA
//  JAMES + PATRICIA
//  RICHARD + ELIZABETH
//  CHARLES + LINDA
//  WILLIAM + MARY
//  or
//  WILLIAM + PATRICIA
//  JAMES + BARBARA
//  RICHARD + ELIZABETH
//  CHARLES + LINDA
//  JOHN + MARY
//  or...
//
Delimeter = " + ";

//===========================================================
//===========================================================
//============ T H E   S C R I P T ==========================

document.selection.SelectAll();
Lines = sel.split("rn");     //Using Windows Line Enders here
SeparatorFound = false;
arrONE = new Array();
arrTWO = new Array();
arrOUT = new Array();

for(L = 0, Ls = Lines.length; L < Ls; L++){
if (Lines[L].indexOf(Separator) != -1){
SeparatorFound = true; continue; //SKIP
}
if (SeparatorFound==false){
arrONE[L] = Lines[L];
}else{
arrTWO[L] = Lines[L];
}
}

//Randomize the order of the array:
arrONE.sort( function() {return 0.5 - Math.random()} );
arrTWO.sort( function() {return 0.5 - Math.random()} );
//Join the arrays side-by-side:
for(idx=0,Len=arrONE.length; idx<Len; idx++){
arrOUT[idx] = arrONE[idx] + Delimeter + arrTWO[idx];
}
//============ O U T P U T =================================
OUT = arrOUT.join("rn");
