My Nickname Is Danger

A few years ago one of my colleagues “discovered” an algorithm which led to my nickname:

• take the 3 first characters of my first name and surname
• concatenate them: DANiel + GERlach => Danger

The algorithm can be implemented as a pure function in Javascript:

1
2
3
4
5
6
7
8
9

function getNickname(fullname) {
  return fullname
    .split(/\s+/)
    .map(n => n.substring(0,3))
    .join('');
}

const result = getNickname('Daniel Gerlach');
console.log(result);   // => DanGer
