As a beginner programmer or developer, have asked yourself what are the differences between these three types of collections, arrays, dictionaries, and lists. In this video, I explain what are the features of each of these collections types. I will explain what an array is and the things you can do with an array. I also explain how in some situations it might be a better idea to use a dictionary instead of an array, I also touch on the advantages of using a list in the .NET ecosystem; whether you are using .NET framework or .NET core.
