JavaScript Front-end Development: Functions & Objects

JavaScript has rich language features for representing and manipulating real world items as data. During this course you will explore the basics of creating and working with functions as well as creating and manipulating objects in JavaScript. Begin by learning how to use function arguments and pass functions as values. Next you will study recursive and arrow functions and learn scoping and how to differentiate between local and global variables. As you progress you will explore JavaScripts more common predefined functions and create custom objects. Other topics include how to employ the FOR/IN loop to retrieve object properties when their names are unknown; how to create custom objects with constructor functions; how to create object methods; how to employ the prototype keyword to add properties and methods to an object. Finally you will learn how to use the PROTOTYPE keyword to implement inheritance and to extend classes.
