javascript abuse, self describing code because it is itself naff. A coworker shared the fail example with me so I expanded a bit.

naff.js

// example: https://jsfiddle.net/conorsheehan1/vqdfsh31/
// runnable in any browser console

// fail (coworker showed me this one)
(![] + [])[+[]] +  (![] + [])[+!+[]] +  ([![]] + [][[]])[+!+[] + [+[]]] +  (![] + [])[!+[] + !+[]];

// Naff
((![] + [][[]]) + [])[+[]] + ((![] + [][[]]) + [])[+!+[]] + (![] + [])[+[]] + (![] + [])[+[]];

// Nooo
((![] + [][[]]) + [])[+[]] + ({} + {})[+!+[]] + ({} + {})[+!+[]] + ({} + {})[+!+[]];
