How to Remember ANSI Escape Codes for Color

ANSI escape codes set the attributes and positioning of text in a terminal. A common use of these codes is to set the text color.

The code "\033[3xm" sets the foreground color x. These values are the decimal representation of a three-bit BGR color:

blue	green	red	binary	decimal (x)	color
0	0	0	000	0	black
0	0	1	001	1	red

// Usually, you'll want to transpose the input (`CARTESIAN_PRODUCT(TRANSPOSE(X1:Y2))`)
function CARTESIAN_PRODUCT(args) {

    return [];
  }

  var first = args[0].filter(function (x) { return x; });

    return first;
