function easyHTTP() {
  this.http = new XMLHttpRequest(); 
}

  easyHTTP.prototype.delete = function(url, data, callback) {

  // BELOW IS THE <<DELETE>> REQUEST IS BEING USED!!!

  this.http.open('DELETE', url, true);
  this.http.setRequestHeader('Content-type', 'application/json');

  let self = this;
  this.http.onload = function() {
  
  // BELOW WE ARE CHECKING IF THE <<HTTP.STATUS>> IS 200

    if(self.http.status === 200) {
      callback(null, self.http.responseText);
    } else {
      callback('Error: ' + self.http.status);
    }
  }
  
  this.http.send(JSON.stringify(data));
}

  callback(null, self.http.responseText);
