JavaScript engineering

JavaScript has had a rather poor reputation among Java developers for some time now. Lack of typing, inconsistent browser implementations and poor testability have led to this image among other factors. It was simply impossible to create high-quality enterprise applications with this language.
However, serious Java web developers have been unable to avoid JavaScript for a number of years now. Yet switching is not easy. The language with its many pitfalls is still quite easy to learn. But where is my build system? How do I test correctly? Should I program functionally or yet again oriented towards the object? Last but not least, there is still the choice of a suitable framework such as Angular or React.
We have already been through this experience and want to convey our acquired knowledge in a compact seminar to hopefully save you many sleepless nights.
