Summary

Modern ES6 supports JavaScript features upwards such as arrow, template literal, destructuring, class, and spread operators. This ability makes code more concise and expressive. Some of the latest features were even available before they were available in browsers thanks to regular V8 updates. (Node.js)

Key points

Arrow function writes a more concise callback and maintains this context
The template literal makes it easy to arrange multi-row strings
Destructing and spreading facilitate the manipulation of arrays and objects
Promise, and optional chaining are fully supported
