The promise is simple: with the right versioning convention, you can trust third-party packages not to break your application unexpectedly. But here’s the uncomfortable truth: Stability in SemVer is more myth than

Unlocking Mutability in TypeScript: How to Remove readonly from Types

Unlocking Mutability in TypeScript: How to Remove readonly from Types

TypeScript is powerful for enforcing type safety, and one of its most useful features is the ability to express immutability through the readonly modifier. However, there are times when we want to reverse that behavior — making a type's properties mutable again. That's where the Mutable<

By using readonly properties, you can ensure that once an object is created, its shape or values can’t be modified accidentally. But sometimes, you do need to mutate the data — especially in scenarios like
