What is the difference between type erasure and type inference?
An example of an AI chatbot conversation about type erasure and type inference in programming languages.
What is the difference between type erasure and type inference?
Type erasure is a process where type information is removed during compilation, while type inference is the ability of the compiler to deduce types automatically.
Can you give me an example of type erasure in Java?
Sure! In Java, generics use type erasure, meaning that the generic type information is not available at runtime. For instance, a List<String> is treated as a List at runtime.
How does type inference work in languages like TypeScript?
In TypeScript, type inference allows the compiler to automatically determine the type of a variable based on its value. For example, if you assign a number to a variable, TypeScript infers its type as 'number'.
Are there any drawbacks to type erasure?
Yes, type erasure can lead to runtime type errors since type information is lost. This can make debugging more challenging.
