Low average skill unfortunately includes them as well. I say unfortunate because, like the build tool developers, they serve an outsized audience with their poorly written apps.

But, to be fair, large tech corporation have many other roadblocks to better software quality, well before you reach testing individual skill levels. Moral decay and office politics to say the least...

I can relate to some "dumbing down" of developer tools and languages. Java and C# are examples and those are fine. But JavaScript?!

Employers are absolutely fixated on gutting developers' salaries and going so far as to building their entire business on molasses by using JavaScript.
