Advanced JavaScript Development

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.
