Introduction to Javascript 2020 part 1


Almost everything in javascript deals with objects, An Object has both properties and methods.
Methods are functions of an object. An object is created by
{} curly braces, also by calling Object() method.

A car is an object
A car has some properties like model and color, and methods like start and stop.

Properties of a car can be its Color, Model, Name or Engine Numbers

 Car = {}.   //Create An Object
 Car.Color = “Red”
 Car.Model = “Mercedes”
 Car.Name = “Benz”

Methods are functions of an object
Car can have a function of start() or stop()

Car.Stop = Function () { //Stop Car}


Functions are block of codes that are created to perform a specified task in our program.

A function will not work until it’s called or invoked, a function entails the function keyword, a function name and can contain some arguments which are optional.

function that add two numbers

Function AddNumber (Num1 + Num2) {
     Return Num1 + Num2

addNumber(4, 6)   //10

in javascript we have
self invoked functions which runs by itself without calling, We have arrow functions which simplify the way we construct our function in javascript.
