extend the json object javascript

Question

javascript code:

window.mybooks={"books": [{"name":"book one","author":"Samuel Peter"},{"name":"book two","author":"Samuel Anderson"}]};

How to add new book to window.mybooks ?

{"name":"book three","author":"Samuel Abelson"}

UPDATE:

strange , a lot of same answers, and not working for me... what can cause this ?

I did found that the object is generated, maybe incorrectly. It looks like this:

window.mybooks={"books": [{"name":"book one","author":"Samuel Peter"},{"name":"book two","author":"Samuel Anderson"},]};

any hints how to correct it and mayabe then push will work ?

Answer 1

window.mybooks.books.push({"name":"book three","author":"Samuel Abelson"});
