About this Guided Project

Learn step-by-step

In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:

  1. Declare a JavaScript variable and assign to it a string value, while demonstrating string-handling techniques.

  2. Use the JavaScript includes() method to search through a string to determine whether it contains a string of characters.

  3. Search through a string using the JavaScript search() method with the goal of returning the position of the matching characters or set of characters.

  4. Search through a string with the JavaScript indexOf() method to return the first occurrence of a specific value.

  5. Search through a string with the JavaScript lastIndexOf() method to return the last occurrence of a specific value.

  6. Locate and replace a value in a JavaScript string using the replace() method.

Recommended experience

Completion of JavaScript Strings - Properties and Methods or basic knowledge of JavaScript is recommended.
