Dense content (depending on my current level: novice in typescript: only reading and adjusting what already exists)Checking pre-requisites: ±50%, to take full advantage of the training, I should have practised a bit more before taking this course. My experience with another language (python) still enabled me to understand the essentials. The theme of the course appealed to me: the trainer is passionate about what he does and passing on his knowledge is a pleasure to receive.
