Don't use switch statement, instead use objects

switch-object.md

Stop using switch like this:

switch(value){
  case 'a':
    console.log('value a');
    break;
  case 'b':
    console.log('value b');
    break;
  default:
    console.log('Default');
}

Instead, use a more elegant way:

let valuess = {
  'a': () => { console.log('value a'); },
  'b': () => { console.log('value b'); }
};
