in JavaScript var x ='yes'
in typeScript var x:string ='yes';
	            var y:number =5;

this is how we define class in JavaScript
function Human(age, name){
this.name = name
this.age = age}
var ray = new Human(18,'Ray')

describing class in TypeScript
class Human{
(properties):
age:number
name:string these two can be defined in the constructor
constructor (age: number, name:string){
this.age = age,
this.name = name
}

functions:
speak(){
console.log('Something')
}

var Ray:Human = new Human(18, 'Ray')

Example
class QB {
team:String,
number:number,
name:string,
constructor(team, number, name){
this.team=team,
this.number=number,
this.name=string
}
stateself(): void{
console.log('i am a $(this.name) and i am playing for the $(this.team),
}
}
