Tell us what’s happening:

Your code so far

var Person = function(str) {
    // Complete the method below and implement the others similarly
    this.getFullName = function() {
      return str;
    };
  this.getFirstName = function() {
      return str.split(" ")[0];
    };
  this.getLastName = function() {
      return str.split(" ")[1];
    };
  this.setFullName = function(firstandlast) {
      str=firstandlast;
        return str;
    };
  this.setFirstName = function(first) {
      var x = str.split(" ");
    x[0]=first;
        return x.join(" ");
    };
  this.setLastName = function(last) {
      var y=str.split(" ");
    y[1]=last;
    return y.join(" ");
    };
    return str;
};

var bob = new Person('Bob Ross');
bob.getFullName();
