Does TypeScript supports function overloading?

Yes, TypeScript supports function overloading. Function overloading in TypeScript allows you to define multiple functions with the same name but with different parameter types or numbers of parameters. This feature enables you to provide different implementations for a function that are executed depending on the types and number of arguments passed to it.

In TypeScript, function overloading is achieved by writing multiple function signatures (overload signatures) for the same function name. These signatures define the possible ways the function can be called in terms of the number and types of parameters. However, you must also provide a single function implementation (implementation signature) that contains the actual code to be executed. This implementation must be compatible with all the overload signatures and is responsible for handling the different types of inputs based on the arguments it receives[1][2][3][5][6][7].

It's important to note that while TypeScript provides syntax for function overloading, the actual function overloading behavior is simulated. TypeScript does this by selecting the appropriate function signature during compile tim...
