javascript - How to prepend a string to a string variable in a for loop without changing the loop structure? -

if have loop this:

var rows; var len = z[0].length; ( var = len; i--; ) {      rows += "<tr><td>" + z[0].marketer + "</td><td>";  }

how can prepend instead of append current row string without changing loop structure?

var rows; var len = z[0].length; ( var = len; i--; ) {      rows (prepend) "<tr><td>" + z[0].marketer + "</td><td>";  }

like this:

rows = "<tr><td>" + z[0].marketer + "</td><td>" + rows;
