In this beginning-level course you will learn and practice new string-handling skills using Notepad++ to write JavaScript code and the Chrome browser to view your results. Since text data is commonly used as a “string” in JavaScript, the ability to use and manipulate strings is a key component in JavaScript programming. You will learn some of the properties and methods that make string handling easier. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
