In the upcoming lecture, we will be creating our store.ts file. You may notice that createStore will have a strikethrough in your code editor. This strikethrough can be ignored as it will have no actual effect on the project or code going forward. This isn't a real deprecation as its only purpose is to encourage the use of Redux Toolkit (which introduces configureStore) instead of using createStore directly. When this course was recorded, we made the purposeful decision to use plain React Redux without any abstractions like Redux Toolkit.
