If you use the IMHO great Handlebars templating library in a real world project you need to write custom Handlebars Helpers. This are functions which return a string and which encapsulate your logic to prevent you and your team to implement business logic in templates.
The method Handlebars.registerHelper has a signature which looks like your bread and butter use case for ES6 arrow functions:
Handlebars.registerHelper( 'important', (...args) => args.join(this.exclamationMark) )` But an arrow function doesn’t bind this it just inherits it from its defining scope.

It is worse than Eclipse.
But the good news is you have to this only for one instance.

For many user interactions you need the user to provide a date or time. And there where a lot of more less good working datepicker. But with rise of mobile it became obvious that a little popup box – with at least 35 little links in it – could be done better.

Wer merkt sich gerne Passwörter? Wer tippt gerne Passwörter ein? Und wer hat für jeden Dienst ein individuelles und sicheres Passwort?
Also ich nicht. Und deswegen hatte ich auch ein schlechtes Gewissen.
