• Array

Store information jen.eyes = 'green' A lot of times in Math you with use a variable to represent a number like:
X = 5
Y = 4

The Value of X is ? 4

My Letter is A
so the variable llama = 'Jen' or "Jen"

The

python

var x = 47

javascript

var x = 47
let y = 23
const = 3

var instructors = ['Jen', "Greg', 'Lionel', 'Other']

Allows is to contol what the program does
if this

Repeat a section of code a set number of times until the process is complete

properties values

var jen = {id:1, firstName: 'Jen', lastName: 'Diamond', email: '[email protected]'}

var jen = {id:1, firstName: 'Jen', lastName: 'Diamond', email: '[email protected]'}

$ jen.name >> 'Jen'

var instructors = [ 
                    {id:1, firstName: 'Jen', lastName: 'Diamond', email: '[email protected]'},
                    {id:1, firstName: 'Lionel', lastName: 'X', email: '[email protected]'},
                    {id:1, firstName: 'Greg', lastName: 'Santos', email: '[email protected]'},
                    {id:1, firstName: 'Jen', lastName: 'Diamond', email: '[email protected]'},
		  ]

Classes hold information about an Object. It is used as a blue print from which you can ceate a new Object

class Animal { 
  constructor(name) {
    this.name = name;
  }
  
  speak() {
    console.log(this.name + ' makes a noise.');
  }
}

class Dog extends Animal {
  constructor(name) {
    super(name); // call the super class constructor and pass in the name parameter
  }

  speak() {
    console.log(this.name + ' barks.');
  }
}

var d = new Dog('Mitzie');
d.speak(); // Mitzie barks.

var r = new Rectangle()
undefined
r
Rectangle {height: undefined, width: undefined}
r.height = 10
10
r
Rectangle {height: 10, width: undefined}
r.width = 20
20
r
Rectangle {height: 10, width: 20}

var rect = new Rectangle(10, 10);

console.log(square.area); // 100
