Make an object
Objekte und Eigenschaften in einem simplen Beispiel umgesetzt.
const Person = function(firstAndLast) {
String.prototype.splitter = function(divider, index) {
return this.split(divider)[index]
};
let firstName = firstAndLast.splitter(" ", 0);
let lastName = firstAndLast.splitter(" ", 1);
let firstAndLastName = firstAndLast;
this.setFirstName = function(first) {
firstName = first;
return this;
};
this.setLastName = function(last) {
lastName = last;
return this;
};
this.setFullName = function(firstAndLast) {
firstName = firstAndLast.splitter(" ", 0);
lastName = firstAndLast.splitter(" ", 1);
return this;
};
this.getFirstName = function() {
return firstName;
};
this.getLastName = function() {
return lastName;
};
this.getFullName = function() {
return firstName + " " + lastName;
};
return firstAndLastName;
};
const bob = new Person('Bob Ross');
bob.setFullName("Haskell Curry");
console.log(bob.getLastName());
No properties should be added. Object.keys(bob).length
should always return 6.
bob instanceof Person
should return true
.
bob.firstName
should return undefined
.
bob.lastName
should return undefined
.
bob.getFirstName()
should return the string Bob
.
bob.getLastName()
should return the string Ross
.
bob.getFullName()
should return the string Bob Ross
.
bob.getFullName()
should return the string Haskell Ross
after bob.setFirstName("Haskell")
.
bob.getFullName()
should return the string Haskell Curry
after bob.setLastName("Curry")
.
bob.getFullName()
should return the string Haskell Curry
after bob.setFullName("Haskell Curry")
.
bob.getFirstName()
should return the string Haskell
after bob.setFullName("Haskell Curry")
.
bob.getLastName()
should return the string Curry
after bob.setFullName("Haskell Curry")
.
