In this tutorial, you will learn about generator functions in TypeScript. Generator functions are functions that return a generator object, which generates data on demand. You will also learn about the differences between iterators and iterables.
This article provides a code example of a Calculator class in TypeScript that can add numbers or strings. The add method converts the inputs to numbers, adds them together, and returns the result as a number or string depending on the input types.
Static methods in programming are functions that can be called directly from a class without needing to create an instance of the class. They are useful when you have a function that doesn't rely on any internal state of the class.
