What are the best practices for runtime type checking in JavaScript?

Some best practices include using libraries like Joi or Yup, leveraging TypeScript for static type checking, and implementing custom type guards.

Can you explain how to use Joi for type validation?

Sure! Joi allows you to define a schema for your data and validate it against that schema. You can create rules for each field, like required, min, max, etc.

What are the advantages of using TypeScript for type checking?

TypeScript provides static type checking at compile time, which helps catch errors early, improves code readability, and enhances IDE support.

Are there any performance concerns with runtime type checking?

Yes, runtime type checking can introduce overhead, especially in performance-critical applications. It's important to balance type safety with performance.
