title: Use class Syntax to Define a Constructor Function
challengeType: 1
---
## Description
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.
## Instructions
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.
## Tests
```yml
tests:
- text: Vegetable should be a class with a defined constructor method.
testString: 'assert(typeof Vegetable === "function" && typeof Vegetable.constructor === "function", "Vegetable should be a class with a defined constructor method.");'
- text: class keyword was used.
testString: 'getUserInput => assert(getUserInput("index").match(/class/g),"class keyword was used.");'
- text: Vegetable can be instantiated.
testString: 'assert(() => {const a = new Vegetable("apple"); return typeof a === "object";},"Vegetable can be instantiated.");'
- text: carrot.name should return carrot.
testString: 'assert(carrot.name=="carrot","carrot.name should return carrot.");'
```
## Challenge Seed
```js
function makeClass() {
"use strict";
/* Alter code below this line */
/* Alter code above this line */
return Vegetable;
}
const Vegetable = makeClass();
const carrot = new Vegetable('carrot');
console.log(carrot.name); // => should be 'carrot'
```
