How to move all uppercase characters to the end of string in JavaScript

Answer 1

function move_uppercase_to_end(s) { 
    var len = s.length;  
    var lowercase = "";  
    var uppercase = "";  
   
    var ch;  
    for (var i = 0; i < len; i++) {  
        ch = s[i] ;  
        if (ch >= 'A' && ch <= 'Z') {  
            uppercase += ch;  
        }  
        else {  
            lowercase += ch;  
        }  
    }  
    return lowercase + uppercase;  
}  
  

var s = "C++ PHP JavaScript";  

document.write(move_uppercase_to_end(s)); 
      
       
  
   
/*
run:
