The challenge of JS is and has always been finding a productive corner of all the possibilities of what you can do with it, and optimizing within that corner.

The challenge of JS is and has always been finding a productive corner of all the possibilities of what you can do with it, and optimizing within that corner. Usually that means picking up a subset of well supported frameworks that you like and find works well in the domain you’re in. It also means learning what language features not to use, or at least abstract away their use. People coming from highly opinionated languages with a large standard library tend to shoot themselves in the foot because they don’t understand this, and nobody really tells them. And inevitably a discussion turns into an argument with different sides becoming Balkanized because they use different parts of the possible language/library set.
