maybe in about 5 years we'll actually be able to use it in browsers.

Up to es2018 is supported in just about everything but Internet Explorer. Even Safari and Mobile Safari would run it without babel. Transpiling to ES5 or ES6 these days is just a preference that not everybody does

according to kangax.github.io/compat-table/es20..., Firefox, Safari, and Edge still don't support all of ES2017. maybe we'll have full ES2017 support across all major browsers in 2022, when non-Chromium Edge is expected to finally die.
