Data Manipulation in JavaScript from Coursera

What's inside

Syllabus

Getting Started & Collecting and Validating Data From Users

In this module, you will be able to review and create HTML form elements, in preparation for doing form validation. You will be introduced to basic form validation and be able to discuss the differences between server side and client side validation, as well as the purpose of each type. You will be able to explore some of the advanced features available in the jQuery validation plugin, and take full control of the way information is presented to users.

A Deeper Dive Into JavaScript

In this module, you will be introduced to the concept of prototypical inheritance in JavaScript, and be able to demonstrate how it affects objects. You will be able to take a deeper look at arrow functions as an alternative to traditional function expression syntax. You will be able to convert function expressions into arrow functions when appropriate. You will be introduced to a larger scripting project with more functionality and complexity, which you will be able to start in the next module.

Seat Reservation Program

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.

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).
