// Are we in the upward slope or downward slope of the business cycle?
// Using m as a chart, get the trend of m over time(indices) to determine whether overall there is currently economic expansion or contraction.
var m = []; // monthly economic output
// m's values will be between 1 and 10 (inclusive)
for(var xint = 0;xint < 10;xint++) m.push(Math.floor(Math.random() * 9) + 1);

// get the overall trend
// the change is the accumulative difference between each index and the first index
