Advanced JavaScript Development

This lesson reviews the essential terms and uses of JavaScript function closures, covering concepts such as lexical scoping, with a series of examples.

This lesson explains the essential concepts for working with variable scope in JavaScript, including the difference between global and local variables.

LearnToProgram walks you through function objects in JavaScript, with examples of using properties, such as constructor, and methods, such as apply.

In this lesson, Marco explains the JavaScript arguments object in depth, from retrieving argument values to determining the length of function parameters.

Event propagation, bubbling, and capturing have to do with the order in which an event passes through elements. Marco explains the difference in this lesson.

Dive into JavaScript objects in this lesson, first by learning about object and property attributes, followed by the steps for defining your own objects.

Learn the difference between inherited and "own" properties, how to create new properties, and how to use methods like hasOwnProperty in this lesson.

Learn how to create a JSON object with a few basic properties, how to retrieve values stored in the object, and how to use the stringify and parse methods.

This lesson guides you through properties, object attributes, and prototypes in JavaScript, reviewing a few simple examples to illustrate key concepts.

Arrays are single variables that can store huge amounts of information. This lesson introduces arrays in JavaScript with essential concepts and an example.

With simple coding examples, see how to read arrays, access sparse arrays, check an array's length, and add and delete elements from an array in this lesson.

In this lesson, learn how to return elements in an array, skipping undefined, non-existent, and null values, and how to create a two-dimensional array.

This lesson presents some of the most useful array methods that are readily available in JavaScript, including join(), splice(), push(), and filter().

This lesson introduces the use of classes in object-oriented programming in JavaScript, including defining new classes and assigning them properties.

In JavaScript, modules take advantage of function scope, making variables local. Marco explains the value of defining modules and namespaces in this lesson.

Continue learning how to define modules and construct namespace objects in JavaScript, from setting up private variables to creating nested namespaces.

In this JavaScript lesson, take a look at the HTML DOM, or Document Object Model, for web pages—including commonly used HTML elements and attributes, and more.

Learn how you can use JavaScript to insert and remove HTML elements on a web page in this short lesson about the DOM node tree and its relationship hierarchy.

HTML DOM Level 3 allows you to use JavaScript to navigate between nodes. Learn some of the properties and methods available, and some ideas for using them.

The XML DOM is the standard for using XML elements on a web page. Learn the available properties, methods, and nodeType properties in these quick examples.

In this short JavaScript lesson, watch an example of how attributes work in the XML DOM. Learn more about node relationships, and how the node tree works.

In this quick JS demo, watch how to add elements to the XML DOM node tree, including how to create, get, and append a new element, and how to clone nodes.

Watch a demonstration of how to delete nodes from an XML tree in this short JavaScript lesson. Learn how to clear text, remove attributes, and more.

In this brief JavaScript demonstration, watch as web developer and instructor Marco Covarrubias shows you how to replace nodes in an XML tree.

Regular expressions in JavaScript are powerful search tools. Learn how to construct them, and how to use RegExp object properties and methods.

Continue learning about JavaScript regular expressions, and watch a few quick examples of how to use RegExp object methods like test() and toString().

In this JavaScript lesson, watch examples of how to construct regular expressions, and see sample code for parsing a number and parsing a URL.

Get an overview of the Browser Object Model (BOM), plus available window object properties and methods in this short JavaScript lesson for web developers.

In this quick JavaScript demonstration, watch examples of how to use window.location, window.navigator, and other window object properties to get browser info.

In this short lesson on how to use the windows history object in JavaScript, learn about using windows history methods and three types of JS popup boxes.

Continuing from the previous JavaScript lesson, these short browser object examples focus on timing events using the setInterval() and setTimeout() methods.
