&gt; JavaScript is intrinsically a dysfunctional language. It has many more flaws than any other programming language in wide use. JavaScript is wholly unsuitable for serious software engineering, esp. at scale. When your application grows to tens of thousands of lines of code, it becomes much more difficult to maintain, much more difficult to ensure a specific level of quality.<p>Replace Javascript with PHP and you get the usual complaint people have about PHP (but there&#x27;s still Facebook). Replace a few words and Javascript with Java and you get another common complaint, still, all these languages are in active use at various companies, so maybe they have their uses?
