Introduction

# Course Review: Data Manipulation in JavaScript ## Overview In the ever-evolving world of web development, the ability to effectively manipulate data is paramount, and there’s no better language for this than JavaScript. The **Data Manipulation in JavaScript** course on Coursera aims to enhance your previous JavaScript skills and equip you with the tools needed to manage and manipulate data, particularly in the context of user input and external data sources. This course is a perfect fit for anyone looking to go beyond the basics and truly understand how to validate, handle, and manipulate data using JavaScript and jQuery. With hands-on challenges and practical projects, including a seat reservation system, you'll be given the opportunity to apply what you learn in a real-world context. ## Course Objectives By the end of this course, you will: - Understand the fundamental differences between server-side and client-side validation. - Gain a solid grasp of validation basics in JavaScript and jQuery. - Learn the features of the jQuery form validation plugin to enhance user experience. - Dive deeper into JavaScript concepts such as prototypical inheritance, arrow functions, and asynchronous JavaScript. - Work on practical projects to manipulate data effectively from the client side. ## Syllabus Breakdown ### 1. Getting Started & Collecting and Validating Data from Users The course kicks off with a focus on collecting user input through HTML forms. You will learn to create and validate forms, understanding the importance of both client-side and server-side validation. This foundational knowledge is crucial, as it sets the stage for handling real user input. ### 2. A Deeper Dive Into JavaScript In this module, you will explore significant JavaScript concepts, including prototypical inheritance and arrow functions. This deeper understanding of the language's intricacies will empower you to write cleaner, more efficient code. You'll also begin a larger scripting project that will challenge your skills and push your understanding of JavaScript to new heights. ### 3. Seat Reservation Program Here, you get to put theory into practice with a hands-on challenge: developing a seat reservation program. You will refactor existing code, address bugs, and utilize DOM manipulation techniques to enhance the user experience. This practical aspect allows you to see how data manipulation works in a real application, from managing objects to providing feedback to users. ### 4. Working with Data Asynchronously in JavaScript Understanding asynchronous data handling is critical in today’s web development landscape. This module introduces you to working with asynchronous methods in JavaScript, exploring how to retrieve data and build dynamic web forms. You will learn about third-party APIs, which is invaluable for modern web development, and have the opportunity to work on an Honors project to further solidify your skills. ## Why You Should Take This Course 1. **Practical Applications**: The course structures its lessons around real-world scenarios. By developing a seat reservation system and engaging with APIs, you will gain practical experience that is directly applicable to jobs in web development. 2. **Comprehensive Learning**: Beyond just handling data, the course delves into advanced JavaScript techniques, which will enhance your overall programming skills. 3. **Community and Support**: Being part of the Coursera community provides you access to fellow learners and support from instructors, allowing for a collaborative learning environment. 4. **Flexibility and Accessibility**: With Coursera's user-friendly platform, you can learn at your own pace, making this course an excellent choice for busy professionals or students. ## Recommendation If you're looking to elevate your JavaScript skills and learn data manipulation in a hands-on, engaging way, **Data Manipulation in JavaScript** is highly recommended. Whether you're aiming to pursue a career in web development or want to enhance your existing skill set, this course provides essential knowledge and practical skills that will be valuable in any developer’s toolkit. In summary, embrace the opportunity to learn, practice, and refine your data manipulation expertise with this comprehensive course on Coursera!

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.

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.

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.

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).
