Type Safety

May 11, 2024 4 minute read

Type safety is a concept in computer programming that refers to the ability of a programming language to detect and prevent type errors. A type error occurs when an attempt is made to perform an operation on a value that is not of the expected type. For example, in a strongly typed language like Java, an attempt to add a string to an integer will result in a type error. In contrast, a weakly typed language like JavaScript will allow such an operation, and the result will be a string concatenation rather than an arithmetic addition.
