In the JavaScript Array.prototype.forEach() method, you can get the index of the current element in the loop by using the (optional) second parameter of the callback function, for example, like so: const
In this, we can iterate the array elements by using a foreach loop in TypeScript. This is very important because we always required something to show the array element one by one and perform operations. This works in the same way as another programming language. But t is more simplified,...
