An example of an AI chatbot conversation about using type checking in programming.
How do I use type checking in my code?
Type checking helps ensure that variables are of the expected type. In languages like TypeScript, you can define types explicitly.
Can you give me an example of type checking in TypeScript?
Sure! In TypeScript, you can define a variable like this: let age: number = 25;. This ensures that age can only hold numeric values.
What happens if I assign a different type to it?
If you try to assign a different type, like a string, TypeScript will throw a compile-time error, helping you catch issues early.
Is type checking available in Python?
Yes, Python has type hints introduced in PEP 484. You can use them with static type checkers like mypy to enforce type checking.
