    It's a bit frustrating when the instructions are incorrect and then fixed a few moments later in the videos. Causes quite the confusion when pausing to catch up and thereby incorrectly writing out the code. Not sure why those sort of mistakes were left in the videos. Good instructions overall though.

    Awesome instructor. Made everything easy to understand. Not only did I learn TypeScript, but he clarified a lot of questions I had about JavaScript and React. I highly recommend this course.

    It's a fine Typescript course for beginners. The second part of the course does however, as many have pointed out, feel like seeing the forest, but not the trees.
