three.js - JavaScript formula to create grid -

im wanting tile grid of objects using javascript.i have forgotten formula, cant seem find online anywhere:

            var width = 113;             var height = 113;             var col = 10;             var row = 10;              ( j = 0; j < col; j ++ ) {                  var object = new object();                  object.position.x = 0 + width * j                  // nee loop here?                  //add object to....              } 

this return row of 10 objects spaced width want columns 10x10 grid, after formula in javascript..

you nest 2 for loops, this:

var width = 113; var height = 113; var col = 10; var row = 10;  var space = ...;  // rows loop ( j = 0; j < row; j ++ ) {      // each column in row      ( = 0; < col; ++ ) {          // j row index , column index..          var object = new object();          object.position.x = (width + space) * i;          object.position.y = (height + space) * j;          // add object to...      }  }
