Short Functions: Arrows

Professional JavaScript is full of little arrow functions — a shorter way to write the same thing, especially when passing a function to another function.

const spinTwice = (name) => { … }

1. 1Arrow version

   Write spinTwice as an arrow function.

   const spinTwice = (name) => {
     spin(name)
     spin(name)
   }

2. 2Call it

   Create a robot and call your arrow function.

3. 3Pass a function

   Use repeat and hand it an arrow function to run three times.
