   @rauschma omitting parentheses is one of the nice syntax sugar I use in my JS code:

   ```js
   const add = a => b => a+b
   ```

     #TypeScript: Arrow functions help with partial evaluation [1] – e.g. a factory for functions for which there already is a type. Then they are more elegant than using .bind() [2]

     const functionFactory = (factoryArg: string): FunctionType => (functionArg) => { … }

     Note that the type of `functionArg` and the result type of the second arrow function are provided by `FunctionType`.
