These are my solutions to the RoboScript series of katas on CodeWars.

This Kata Series is based on a fictional story about a computer scientist and engineer who owns a firm that sells a toy robot called MyRobot which can interpret its own (esoteric) programming language called RoboScript. Naturally, this Kata Series deals with the software side of things (I'm afraid Codewars cannot test your ability to build a physical robot!).

• RoboScript #1 - Syntax Highlighting
  • remarks: pretty simple and straight-forward
  • tip: don't chain .replace calls as it can lead to unexpected results
  • hint: replacer function
• RoboScript #2 - RS1 specification
• remarks: needed to sit and think for a lil' while

Ninja code

Learning without thought is labor lost; thought without learning is perilous.

— Confucius

Programmer ninjas of the past used these tricks to sharpen the mind of code maintainers.
Code review gurus look for them in test tasks.
Novice developers sometimes use them even better than programmer ninjas.
Read them carefully and find out who you are – a ninja, a novice, or maybe a code reviewer?
