Comparing Javascript to other dynamic languages its comparable and indeed has some nice features - e.g. self style prototypes. If you compare it to more type safe languages like Java, C, Swift, Kotlin etc then it has major flaws. The dynamic languages are great for making little scripts or small-medium size one man projects, they fall down when you need to build something larger with lots of people and lots of code. If you include the problems of javascript with running it into the limited environment of the browser then there is much room for complaint.

I think a lot of the arguments are due to the clash of these two opposing mindsets, people who start in javascript and build things in a browser think it's great, people who build enterprise applications with typed languages disagree, often strongly.
