In this module, you will given a possible solution to the challenge presented to you in the previous module. You will be able to refactor code using best practices and fix final bugs in the application. You will be able to create a general function for getting data from the seatReservations object and use DOM manipulation techniques and logical flow control structures to update the necessary elements on the web page. You will be able to use JavaScript to create 300 unique objects following a specific naming pattern and be able to demonstrate refactoring code and DRY principles in programming. You will be able to solve possible errors the user may encounter when reserving seats and be able to display and hide the seat reservation form. You will be able to add data to an object based on user selection in the interface and practice DOM manipulation techniques.

WEEK 4
Working with Data Asynchronously in JavaScript
In this module, you will be introduced to asynchronous JavaScript and explore methods for retrieving data asynchronously. You will be able to explore the way JavaScript handles events in more detail and be able to use methods in JavaScript to both send and receive data from a server file, and build a usable contact form for a website. You will be introduced to third party APIs and be able to use asynchronous methods for retrieving and displaying information from these APIs. You'll also be able to explore ways the data coming from third party APIs can be manipulated. You will also have the chance to work on an Honors project (if you desire).
