Search a String Variable with JavaScript Methods

In this intermediate-level project you will write JavaScript code to search through a string variable. You’ll use a variety of JavaScript methods to locate values within a string to determine whether they exist, find their position in the string, or even replace them with other values. The Notepad++ editor and Chrome browser are used to write inline JavaScript code and view the results.

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.
