JavaScript, Part 2 of 6: Objects, Arrays, and Expressions

Course description

JavaScript is the programming language of the World Wide Web, the code that makes a Web page come alive. This course will focus on Objects, Arrays, and Expressions. The course is focused on Creating, Manipulating, Using, and Inheritance of Objects, followed up by Arrays, and Regular Expressions.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes that you have at least some programming experience in one or more modern programming languages. JavaScript will be particularly easy for you to learn if you have experience with any C-style languages—including Java, C#, C++, or Visual Basic .NET would be helpful—but this is not required. The focus here is not on programming concepts but on the structure, syntax, and use of the JavaScript language.
