Futuro do Subjuntivo - Quando vós programardes JavaScript

Quando eu falar sobre JavaScript, vós entendereis o que quero dizer.
Quando tu aprenderes mais sobre JavaScript, serás recompensado.
Quando nós estudarmos sobre o futuro do JavaScript, melhores desenvolvedores nos tornaremos.
Quando vós programardes JavaScript, uma nova aplicação nascerá.
Quando eles souberem sobre as novas features do JavaScript, abismados ficarão.

Palestra apresentada na Webbr Setembro/2015 e no FrontEnd Carioca Setembro/2015.
