So, it is recommended that before proceeding with this tutorial you must read about the overview of Typescript which contains the basic information that what Typescript is and how it converts the Typescript code into the Javascript code.
With forEach, you provide an iterator function which TypeScript calls for each element in the array, providing it with the index, the element and the whole array as parameters. Now in this tutorial, we will learn about the loop and Array in Typescript. For Each Arrays in TypeScript have many different methods attached to them, one of them being the forEach () method.
In the previous tutorial, we had learned about the types of variables in Typescript.
