Liskov Substitution Principle in JavaScript and TypeScript

Read Original

This technical article delves into the Liskov Substitution Principle (LSP), one of the five SOLID principles of object-oriented design. It explains the principle's core requirement that subclasses must be substitutable for their base classes without altering program correctness. Using JavaScript and TypeScript code examples, it illustrates both proper adherence to and violations of the LSP, focusing on method signatures, return types, and exception handling in class inheritance.
