What is Type Inference?
Type inference is the automatic deduction of the data type of an expression in a programming language. Instead of explicitly declaring the type of a variable, the compiler or interpreter can infer it based on the value assigned to it or how it's used within the code. This reduces the need for verbose type annotations, making code more concise and readable while still providing the benefits of type safety.
