One thing zero dependencies bring is the size would become huge.

Another thing is people either:

1. Use their own boring abstraction every time, and every abstraction might be different. 2. Not using abstraction at all, this makes JavaScript more like C code base.

Of course, I'm not saying it's not fragile now. But probably the answer is not as simple as dependency free. Some dialect provides interfaces (like TypeScript), type-classes (yet to be seen in mainstream dialects but I believe this really helps when dealing with fragility because Java could also be fragile because of nominal typing without having type-class) might help in the future.
