Script Preparation code:


var xOffset = 0;
var xScale = 1;
var i = 0, l = 10000000;

function getX( index ) {
  return xOffset + index * xScale;
}

var j = 0;
var tot = 0;

Tests:

test1
for( ;j < 10; j ++ ) { for( i = 0; i < l; i ++ ) { tot += getX( i ); } }
test2
for( ;i < l; i ++ ) { arr[ i ] = xOffset + i * xScale; } for( ;j < 10; j ++ ) { for( i = 0; i < l; i ++ ) { tot += arr[ i ]; } }
