Explore different features available in Javascript to manipulate elements of a web page by using its Document Object Model (DOM) structure and how Javascript interacts with a browser by using the Browser Object Model (BOM). In this 13-video course, key concepts covered include how to use the document object to retrieve individual elements of a web page and access their values and properties; how to alter web page contents by modifying a DOM; and how to retrieve children of elements of a web page as an array. Begin by observing how to write a function to generate an animation; how to define event listeners and handlers for clicks on web page buttons; and how to create handlers for events of users by clicking on buttons. Next, learners observe how to use handlers for mouse events on web page elements; how to use the screen, window, and navigator objects of BOM to get information about the end-user's environment; and how to use the window object to interact with the end-user's browser.
