const x = 4;

if(x === 10){  //=== will match the data type, as well.
    console.log('x is 10');
} else if(x > 10){
    console.log('x is greater than 10');
} else{
    console.log('x is less than 10');
}

const x1 = 4;
const y1 = 11;

if(x1 > 5 || y1 > 10){  //or statement
    console.log('x is more than 5 or y is more than 10');
}

const x2 = 6;
const y2 = 11;

if(x2 > 5 && y2 > 10){  //and statement
    console.log('x is more than 5 or y is more than 10');
}

const z = 11; //Turnurary operator (?? not sure about these yet)
const color = z > 10 ? 'red' : 'blue';
console.log(color);

switch(color){
    case 'red':
        console.log('Color is red.');
        break;

//Basic Functions
function addNums(num1 = 1, num2 = 1){  //default values can be overridden
    return num1 + num2;
}
console.log(addNums(5,6));  //passing numbers through this function

// Arrow functions
const addNums2 = (num1 = 1, num2 = 1) => num1 + num2;  //default values can be overridden
console.log(addNums2(5,5));

// Arrow functions
const addNums3 = num1 => num1 + 5;  //function addNum3 = a number and returns that number + 5
console.log(addNums3(3));

//Object Oriented Programming

//Constructor Functions

/*
function Person(firstName, lastName, dob){
    this.firstName = firstName;
    this.lastName = lastName;
    this.dob = new Date(dob);  //can put in different date forms.
    // this.getBirthYear = function(){
    //  return this.dob.getFullYear();
    //}
    //this.getFullName = function(){
    //  return `${this.firstName} ${this.lastName}`;
    //}
}

Person.prototype.getBirthYear = function(){
    return this.dob.getFullYear();
}
Person.prototype.getFullName = function(){
    return `${this.firstName} ${this.lastName}`;
}

*/

//Class.  Does the same as above, just prettier.

class Person {
    constructor(firstName, lastName, dob){
        this.firstName = firstName;
        this.lastName = lastName;
        this.dob = new Date(dob);
    }
    getBirthYear(){
        return this.dob.getFullYear();
    }
    getFullName(){
        return `${this.firstName} ${this.lastName}`;
    }
}
//instantiate object with constructor function

const person1 = new Person('John', 'Doe', '19 March 2019');
const person2 = new Person('James', 'Dobbs', '4-25-2000');
        // console.log(person1);
        // console.log(person2.dob); // gets only dob
        //console.log(person1.getBirthYear());
        //console.log(person2.getFullName());
console.log(person2.getFullName());
console.log(person1);
