TypeScript for Beginners - Object Casting

The video tutorial explains the concept of object casting and interfaces. It begins by defining an employee interface with an ID field and creating variables E1 and E2. E1 is an employee with a single property, while E2 has additional properties. The tutorial demonstrates assigning E2 to E1 without issues, but highlights problems when assigning E1 to E2 due to missing properties. It emphasizes that typecasting works only if the type members of the first variable are contained within the second variable.
