What are the methods to access javascript properties and methods?

we can use dot and brackets to access the properties and methods.

function myobjs(){

this.name= “john”;  //Property
this.age= “20”;   //Property
this.nameandage= function(){   // Method
console.log(this.name+’with age’+this.age);

},
this.nickname=[“a”,”b”,”c”];  // using multiple values to a property , like array

this.allname=function(){
alert(“eachname”);
this.nickname.forEach(function(eachname){
alert(eachname);
});
}
}
var insta_myobj=new myobjs();
alert(insta_myobj[‘name’]); // brackets
insta_myobj.allname();        // dot
