What is the “get” keyword before a function in a class?

Question

What does get mean in this ES6 class? How do I reference this function? How should I use it?

class Polygon {
  constructor(height, width) {
           


        

Answer 1

It is getter, same as Objects and Classes in OO JavaScript. From the MDN Docs for get:

The get syntax binds an object property to a function that will be called when that property is looked up.
