TypeScript for Beginners - Introduction - Interfaces

The video tutorial explains the creation of objects using object literal syntax and highlights the inconsistency issues that can arise in large applications. It introduces interfaces in TypeScript as a solution to enforce a standard set of rules for objects, functions, arrays, and classes. Interfaces act as a contract, ensuring that objects comply with specified properties and methods. Unlike inheritance in languages like Java, TypeScript interfaces are strictly for defining contracts and are only relevant at compile time. The tutorial also discusses the versatility of interfaces, which can be applied to various programming constructs.
