Evaluating alternatives to TypeScript’s switch case
Blog post from LogRocket
Switch case statements in TypeScript are a topic of debate due to their verbosity and potential for errors, particularly in large-scale projects. While they offer benefits like elegance and performance compared to lengthy if-else blocks, they can become cumbersome and less maintainable as projects expand. Alternatives such as object lookup tables and object-oriented programming (OOP) principles like polymorphism and inheritance are suggested for better maintainability and readability. Object lookup tables provide a less verbose option but involve trade-offs in time and memory efficiency. OOP techniques, on the other hand, provide a more robust framework by allowing for easy modification and extension without violating software design principles like the open-closed principle. These alternatives are recommended for more scalable and maintainable codebases, especially in projects that may grow in complexity and size.
