TypeScript for Beginners - Creating a class

The video tutorial guides viewers through creating a TypeScript class named 'Passenger' with properties like first name, last name, and frequent flyer number. It covers setting up the development environment, defining the class, creating objects, and accessing properties. The tutorial also addresses compiling the code and troubleshooting common issues, such as uninitialized properties, which will be resolved in a subsequent lecture.
