• Revising TS with Full-Stack React, TS & Node.
• Revising how private ,readonly and static keywords are used in classes.
• static types cant only be accessed via the class name, therefore references to a class static property is forbidden. static type are therefore useful for sharing state across multiples instances of the same class.
• Revising how inheritence works in JS. When inheriting a class, the super keyword is the reference to the parent class you are inheriting from.
  • the protected keywords means that the property is still private to the class but anything inheriting the class has access to the member.
• namespaces in TS provided another level of encapsulation. Similar to classes in a way, but it is possible contain many classes.
