Is point within a rectangle

I came up with this neat function to check if a point [x,y] is within a rectangle [x, y, width, height].

It´s made in Javascript but can be applied to ALL languages.

// Comment
Utils.pointWithinRect = function(point, rect) {
  var px     = point[0];
  var py     = point[1];
  var top    = rect.y;
  var left   = rect.x;
  var bottom = rect.y + rect.height;
  var right  = rect.x + rect.width;
  return (px >= left && px = top && py <= bottom);
 }
