-## Const as much as possible
-`const` tells the compiler that a variable or method is immutable. This helps the compiler optimize the code and helps the developer know if a function side effects. Also, using `const &` prevents the compiler from copying data unnecessarily. [Here](http://kotaku.com/454293019) are some comments on const from John Carmack.
