parsing string in javascript

I have string MetadataCompanyTotal which is Camel Case. I need to insert space between string.

Input is

var str="MetadataCompanyTotal";

output should be 

"Metadata Company Total".

I have tried the following approach but needed a faster way with less number of lines as there is lines constraint.

My approach : 

var i, 
    str="MetadataCompanyTotal",
    temp_str="",
    final_space_inserted_str="";

for(i=0; i < str.length ; i++){
   if ( str.charAt(i) === str.charAt(i).toUpperCase()){
      final_space_inserted_str += temp_str + " ";//inserting space.
      temp_str = str.charAt(i);
   }
   else{
      temp_str += str.charAt(i);
      }
}


final_space_inserted_str+=temp_str.// last word.

Is there any efficient approach in javascript?

Use regex to replace all upper case with space before and trim to remove first space.

var CamelCaseWord = "MetadataUSAddressType";

alert(CamelCaseWord.replace(/([A-Z])([A-Z])([a-z])|([a-z])([A-Z])/g, '$1$4 $2$3$5').trim())
