I just realized this morning that JavaScript is the new Java.

js targets the browser (angular, React...), the back-end (node), the desktop (Electron) and mobile (React native). Just like the Java of old with applets, javax, JME, and of course weblogic and friends, js today allows you to code anything, as long as you don’t mind doing it badly, insecurely and/or wastefully.

Due to this ubiquity, a large majority of job openings list js in one form or another as a prerequisite (remember when entreprise code was synonymous with Java?)

Once you know enough js to be dangerous, there’s little incentive to pick up another programming language.

As a C++ developer who had to learn Javascript and Vue to write an Electron app, it was still faster than writing the same app in QT (which I used before).

Of they can just use QML and use JavaScript and a declarative language for their UI.
