In javaScript objective programming...

Question

How can we make such that
This code :
obj("ball").throw() ;
returns Ball is thrown

How can be defined this?

Answer 1

function obj(arg){
if(arg==="ball")
return{
throw: function(){
console.log("Ball is thrown");
}
}
else{
return;
}
}
// Now this will return what you expect
obj("ball").throw();

But that isn't object orientated programming!!!
Better is doing this:

function Ball(){
this.throw=function(){
console.log("Ball is thrown“);
}
}
var ball= new Ball();
ball.throw();

Answer 2

Rebeka thanks.

Answer 3

maybe with a boolean variable that changes to true once the ball is thrown
