What are some real-world examples of type checking?

Type checking is used in programming languages to ensure that variables are used consistently. For example, in languages like Java, type checking helps catch errors at compile time, ensuring that a variable declared as an integer isn't assigned a string value.

Can you give me more examples of where type checking is beneficial?

Sure! In web development, type checking can prevent runtime errors by ensuring that data types match expected formats, like validating user input in forms. In data science, type checking helps maintain data integrity when processing datasets.

What programming languages use type checking?

Languages like Java, C#, and TypeScript use static type checking, while Python and JavaScript use dynamic type checking. Each has its own advantages depending on the use case.

How does type checking improve code quality?

Type checking improves code quality by catching errors early in the development process, making the code more robust and easier to maintain.
