In this course you will build a library that will enhance the browser’s localStorage into a collections based database that will store collections of multiple items. The library you will build will also allow you to find collection items by their ids, update individual collections items, and remove items by ids. Also you will learn about data types and type checking by building helper functions. You will build a class and its methods and create an instance from the class and apply the methods that your just created.
You will also learn about debugging your code as we will use the browser’s inspector to walk through our code line by line and examine values and states of different variables.
