JavaScript, ES6, ES7, ES10 where are we?

What is JavaScript? According to Wikipedia, it is a scripting language that conforms to the ECMAScript specification. ES6, ES7, etc… You probably have heard those names, you also have most likely been using ES6 for a while (with Babel in a lot of cases).

I’m sure most of you are using many different fancy ES6 features without asking yourself: Is this really ES6, is this still a feature…
