Use class Syntax to Define a Constructor Function - pulkitbhutani/My-FreeCodeCamp-Code GitHub Wiki

ES6 provides a new syntax to help create objects, using the keyword class.

This is to be noted, that the class syntax is just a syntax, and not a full-fledged class based implementation of object oriented paradigm, unlike in languages like Java, or Python, or Ruby etc.

In ES5, we usually define a constructor function, and use the new keyword to instantiate an object.

var SpaceShuttle = function(targetPlanet){
  this.targetPlanet = targetPlanet;
}
var zeus = new SpaceShuttle('Jupiter');

The class syntax simply replaces the constructor function creation:

class SpaceShuttle {
  constructor(targetPlanet){
    this.targetPlanet = targetPlanet;
  }
}
const zeus = new SpaceShuttle('Jupiter');

Notice that the class keyword declares a new function, and a constructor was added, which would be invoked when new is called - to create a new object.

Use class keyword and write a proper constructor to create the Vegetable class.

The Vegetable lets you create a vegetable object, with a property name, to be passed to constructor.

Solution-

function makeClass() {
  "use strict";
  /* Alter code below this line */
class Vegetable{
  constructor(vegetableName){
    this.vegetableName = vegetableName;
  }
}
  /* Alter code above this line */
  return Vegetable;
}
const Vegetable = makeClass();
const carrot = new Vegetable('carrot');
console.log(carrot.name); // => should be 'carrot'
