What are some real-world examples of type safety in programming?
Type safety ensures that variables are used consistently with their data types. For example, in Java, if you declare a variable as an integer, you cannot assign a string to it.
Can you give me more examples from different programming languages?
Sure! In C#, type safety prevents you from assigning a string to an integer variable. In TypeScript, it allows you to define types for variables, enhancing code reliability.
How does type safety help in preventing bugs?
Type safety helps catch errors at compile time rather than runtime, reducing the chances of bugs and making the code easier to maintain.
Are there any languages that are not type-safe?
Yes, languages like JavaScript and PHP are considered less type-safe because they allow more flexibility with variable types, which can lead to runtime errors.
