How to use an array of values in javacript?

As usual arrays we can add values into an array variable using commas as separator along with other properties.

function myobjs(){

this.name= “john”; //Property
this.age= “20”; //Property

this.nickname=[“a”,”b”,”c”]; //Array

this.allname=function(){   // array values using in function
this.nickname.forEach(function(eachname){
console.log(eachname);
});
}
}
var insta_myobj=new myobjs();
insta_myobj.allname();
