type inference

Type inference is a process used in programming languages to automatically determine the data types of variables and expressions without explicitly specifying them. For example, if you assign a number to a variable, the language infers that it is of numeric type. This allows programmers to write cleaner code, reducing the need for explicit type declarations. It helps catch errors early and makes code easier to read, while still ensuring that data is used consistently throughout the program. Essentially, type inference makes programming more efficient by letting the computer figure out types behind the scenes.
