Type safety

Type safety refers to a programming concept that ensures variables are used consistently with their intended data types, such as numbers, text, or lists. This helps prevent errors, such as trying to perform mathematical operations on text. In type-safe languages, the system checks that the operations and data types match correctly, reducing the risk of mistakes and improving program reliability. Think of it like ensuring you only use specific tools for certain tasks; using the wrong tool can lead to failures or accidents. Type safety promotes clarity and stability in software development.
