We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

Eladr tokens are designed to incentifised community members as a proof of contribution. Using that they can access diffrent infrastructure built on top of eladr


Using this You can,Buy courses,Reward others and exchange for real money.

In TypeScript, you can inherit a class from another class. Just use the extends keyword to perform inheritance. Consider the following example to understand it better.

class Person {
 // properties
 firstName: string;
 lastName: string;
 // construtor
 constructor (fName: string, lName: string) {
  // fill the properties
  this.firstName = fName;
  this.lastName = lName;
 }
 // method
 getFullName() {
  return `${firstName} ${lastName}`;
 }
}
class Employee extends Person {
 // properties
 empID: string;
 designation: string;
 // construtor
 constructor (fName: string, lName: string,
     eID: string, desig: string) {
  // call the base class constructor
  super(fName, lName);
  // fill the other properties
  this.empID = eID;
  this.designation = desig;
 }
 // method
 toString() {
  return `${empID} - ${firstName} ${lastName}
    => ${designation}`;
 }
Here the Employee class inherits its base Person by writing class Employee extends Person. In the derived class super(...) can be used to call the constructor of the base class. For example, super(fName, lName) in Employee class constructor calls the base class constructor by passing the parameter values fName and lName.

TypeScript supports single inheritance and multilevel inheritance. We can not implement hybrid and multiple inheritances using TypeScript. The inheritance uses class-based inheritance and it can be implemented using extends keywords in typescript.
