Function Overloading in TypeScript

Implementing Function Overloading in TypeScript

This function is overloaded.

Function overloading in TypeScript provides a way to have multiple function signatures for a single function implementation. This feature is particularly useful when you want a function to accept different types or numbers of arguments and behave accordingly. TypeScript’s approach to function overloading is somewhat different from traditional languages like Java or C#. It leverages static type checking to allow multiple “overloads” or “signatures” for a function, but it requires a single implementation that can handle all these overloads.

Here’s a step-by-step guide to implementing function overloading in TypeScript:

Define Function Signatures

The first step is to define all the possible signatures for the function. These signatures only describe the types and number of parameters and the return type of the function. They do not contain any implementation details.

Implement the Function

After defining the signatures, you implement the function. The implementation must be compatible…
