New Syntax in ES6
Deepak Grover, Hanu Prateek Kunduru · Apress eBooks · 2017
The new features introduced in ECMAScript 6 represent the foundation upon which JavaScript applications will be built in the future. In this chapter we will take a look at the changes and new additions to the ES6 syntax that help in fixing a lot of things that went wrong with the previous versions of JavaScript. We will discuss in detail about new ways of declaring variables and defining scope. We will also introduce new concepts like arrow functions, default function parameters, spread and rest operators, and object literal extensions. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
