This course is the third in our JavaScript for Beginners Specialization. The scripts will become more complex and introduce more complex jQuery plugins. You will have several challenges to practice your skills throughout the course. The course objectives include how to identify objects in JavaScript; create new objects and populate them with data; manipulate objects by adding, modifying and deleting data in objects; manipulate the DOM based on the data in objects; identify and articulate how multiple functions work together to create a more complex program; and identify processes for breaking larger programs into smaller, more manageable pieces.

This course builds on the skills from the previous course and goes further into managing and manipulating data with JavaScript. You will learn methods for validating and handling data provided by users or coming from an external data source. This course includes a challenge in the form of a seat reservation system, as well as a project that pulls data in from an external data source.

The course objectives include validation basics in JavaScript and jQuery; jQuery form validation plugin features; arrow functions; asynchronous functions; and the JavaScript event loop.
