Sometimes you may encounter members that have really long member names, such as thisIsWayTooLongOfAName(). In this case, you can import the member and give it a shorter name to use in your current module: import {thisIsWayTooLongOfAName as shortName} from 'module' shortName() You can import m...

Git lets you use non-git commands and full sh shell syntax in your aliases if you prefix them with !. In your ~/.gitconfig file: [alias] temp = !git add -A && git commit -m "Temp" The fact that full shell syntax is available in these prefixed aliases also means you can us...

type Meter = Double This simple approach has serious drawbacks for unit handling as every other type that is a Double will be compatible with it: type Second = Double var length: Meter = 3 val duration: Second = 1 length = duration length = 0d All of the above compiles, so in this case un...

Aliases are named shortcuts of commands, one can define and use in interactive bash instances. They are held in an associative array named BASH_ALIASES.
