![]() ![]() Therefore, when used with arrays, we can get the index of the element stored within the array data because it’s stored as an enumerable string property xdg = īut it also means that we might get access to properties that we might not need. Objects contain enumerable string properties that can be accessed, and the for.in loop allows us to access them directly. In this article, we will discuss how to get index in for.of JavaScript and the different methods to achieve this. for.of allows us to access the element of the array directly without having to use any index value which is typically inserted into the array square notation ( arr[index). In JavaScript, the for loop can be achieved in different ways - for, for.in, for.of, and forEach - which are useful for different case scenarios. ![]() The index value is a popular interface within any loop iteration (whether for or while) that can help access the elements within an iterable or sequences (e.g., array) which can be elusive for certain loop types.
