Generally, the course is divided into 4 lessons, with each lesson handling a group of core concepts introduced with the ‘new’ spec. These 4 lessons are:
Here better ways to create variables were introduced as well as more convinient methods for string interpolation and creating objects.
Both Array and Object destructuring was also touched on here and a new kind of loop was introduced too. And yeah, two new ‘convinience’ operators.
The shorter arrow function expression, default function params and new ways to create classes were touched on here.
The new JS data type
Symbol, Sets & Weaksets, Maps & Weakmaps, Promise, Proxies andd Generators were discussed here.
Nothing new to learn, just (very) helpful hints.
