If anything, this understates the problem. A modal web application today takes an absolute minimum of five programming languages and three frameworks:

    * HTML
    * CSS
    * JS
    * A server-side language (eg Python)
    * SQL

And then come the (leaky) abstractions on top of them:

    * A framework to make JS bearable (eg Angular)
    * A framework to make server-side bearable (eg Django)
    * A framework to make CSS bearable (eg Bootstrap)

...and often...

    * A framework to make SQL bearable (eg SQLAlchemy...)

When someone asks me how to learn to build web apps - even someone who can already program a bit - I feel embarrassed explaining to them what a pile of patches the Web is. Even if the languages themselves were saner, this is a monstrous amount of complexity for something that takes one language and a drag'n'drop GUI builder on any other platform.

Trying to fix this, at least for simple apps, is why we built Anvil - https://anvil.works - where everything is in Python, and the GUI is drag'n'drop.
