Способы применения JavaScript сильно изменились за последнее время. Но сам язык начал меняться только сейчас. Я расскажу вам, что нового нас ожидает в E…
In this presentation we will go over some of the new features of the modern JavaScript. We will get a quick introduction of how to embrace the new features, how to navigate through them, and how not to get overwhelmed. There will be some examples of the more useful features that you will want to understand and begin to adopt.

But other features will change the way we program JavaScript, fundamentally expanding the capabilities of the language and reshaping our future codebases. In this talk we'll focus on two of these, dis
