JavaScript IV

This challenge focuses on classes in JavaScript using the new class keyword.

Assignment Description

You already pretty much know all about classes but you're used to seeing them built in the following context:

function Person(personAttributes)  {
  this.name = personAttributes.name;
  this.age = personAttributes.age;
  this.location = personAttributes.location;
}

const fred = new Person({
  name: 'Fred',
  age: 37,
  location: 'Bedrock'
});

• Because none of the above code is new, you're about to see your world get much much easier when dealing with Object Creation and Classical Inheritance as it pertains to JavaScript.
• The Class Keyword makes this SO MUCH EASIER!
• Fork and clone this repository.
• Complete all of the exercises found in the assignment files.

prototype-refactor - Take existing code and make it modern.

• You're going to work with your prototypes assignment you built out yesterday.
• Challenge: Convert all of your constructors into ES6 Classes using the class and extends keywords. You should be able to run your same logs and they should build out the proper expected behaviors.

lambda-classes - We need a roster of Lambda School personnel. Build it!

• We have a school to build here! This project will get you used to thinking about classes in JavaScript and building them from a brand new data set.
• Lambda personnel can be broken down into three different types of people.
  • Instructors - extensions of Person
  • Students - extensions of Person
  • Project Managers - extensions of Instructors
• IMPORTANT - You'll need to create 2 - 3 objects for each class and test them according to their unique Attributes. For example:

const fred = new Instructor({
  name: 'Fred',
  location: 'Bedrock',
  age: 37,
  gender: 'male',
  favLanguage: 'JavaScript',
  specialty: 'Front-end',
  catchPhrase: `Don't forget the homies`
});

Person

• First we need a Person class. This will be our base-class
• Person receives name age location gender all as props
• Person receives speak as a method.
• This method logs out a phrase Hello my name is Fred, I am from Bedrock where name and location are the object's own props

Instructor

• Now that we have a Person as our base class, we'll build our Instructor class.
• Instructor uses the same attributes that have been set up by Person
• Instructor has the following unique props:
  • specialty what the Instructor is good at i.e. 'redux'
  • favLanguage i.e. 'JavaScript, Python, Elm etc.'
  • catchPhrase i.e. Don't forget the homies
• Instructor has the following methods:
  • demo receives a subject string as an argument and logs out the phrase 'Today we are learning about {subject}' where subject is the param passed in.
  • grade receives a student object and a subject string as arguments and logs out '{student.name} receives a perfect score on {subject}'

Student

• Now we need some students!
• Student uses the same attributes that have been set up by Person
• Student has the following unique props:
  • previousBackground i.e. what the Student used to do before Lambda School
  • className i.e. CS132
  • favSubjects. i.e. an array of the student's favorite subjects ['Html', 'CSS', 'JavaScript']
• Student has the following methods:
  • listsSubjects a method that logs out all of the student's favoriteSubjects one by one.
  • PRAssignment a method that receives a subject as an argument and logs out that the student.name has submitted a PR for {subject}
  • sprintChallenge similar to PRAssignment but logs out student.name has begun sprint challenge on {subject}

Project Mananger

• Now that we have instructors and students, we'd be nowhere without our PM's
• ProjectManagers are extensions of Instructors
• ProjectManagers have the following uniqe props:
  • gradClassName: i.e. CS1
  • favInstructor: i.e. Sean
• ProjectManangers have the following Methods:
  • standUp a method that takes in a slack channel and logs `{name} announces to {channel}, @channel standy times!​​​​​
  • debugsCode a method that takes in a student object and a subject and logs out {name} debugs {student.name}'s code on {subject}

Stretch Problem

• Extend the functionality of the Student by adding a prop called grade and setting it equal to a number between 1-100.
• Now that our students have a grade build out a method on the Instructor (this will be used by BOTH instructors and PM's) that will randomly add or subtract points to a student's grade. Math.random will help.
• Add a graduate method to a student.
  • This method, when called, will check the grade of the student and see if they're ready to graduate from Lambda School
  • If the student's grade is above a 70% let them graduate! Otherswise go back to grading their assignments to increase their score.
