Lab description

JavaScript is one of the most popular programming languages around. Your effort invested in learning JavaScript can take your career to many places. This lab challenge will help you confirm your knowledge in topics covered in the JavaScript for Beginners Path

In this lab challenge, you will be provided with a web browser-based integrated development environment (IDE) with incomplete code for a calculator app. Each step will add features to the app and must be completed before the time runs out.  This is a real environment, which means you can prove your knowledge in an applied situation, leaving behind multiple choice questions for a dynamic performance-based exam situation.

Note: For the lab validation system to function properly, the steps and checks need to be done in order as stated by the instructions.
