>> You can learn React in a day. You can't build an application using React alone. You also need to learn ReactRouter and Redux, which add lots of complexity. Not to mention, if you spent only one day learning React you're probably going to do it wrong: you have to learn things like where to put state, when you have a hierarchy of components. Learning the "ten functions" of the API isn't enough!
