Javascript gives the option to inherit properties and methods by prototype. A simple example follows:
//Serves as "class" like known e.g. in C++ or Java
function myClass()
{}
//Now a property for "myClass" is defined
//Name of property does not have to be "Property"
myClass.prototype.Property = "House";
//Now a method for "myClass" is defined
//Name of method does not have to be "Method"
myClass.prototype.Method = function()
{
return "Blueprint for House";
}
//An instance of "myClass"
var Child = new myClass();
//Outputs string value "House"
console.log(Child.Property);
//Outputs string value "Blueprint for House"
console.log(Child.Method());In the listing above an instance of myParent is done with the keyword new.
Every instance has its own properties and methods. A change from one instance should not influence the properties and methods from another instance. For clarification an example follows:
//Serves as "class" like in C++ or Java
function myClass()
{}
//Now a property for "myClass" is defined
myClass.prototype.Property = "House";
//Two Instances
var ChildOne = new myClass();
var ChildTwo = new myClass();
//Changing Property of "ChildOne"
ChildOne.Property = 42;
//Outputs 42
console.log(ChildOne.Property);
//Outputs the string value "House",
//because the change is only done within instance "ChildOne"
console.log(ChildTwo.Property);🥇 TODO: Complete table - STILL IN WORK!
