In my experience both as a developer and later as a manager, learning "on the job" never led to a good outcome. The (implicit or explicit) deadline pressure always led to the most shallow comprehension, weak scrutiny of Googled code and 'first hit' adoption of libraries or other secondary assets, very slow error correction and a cascade of (I hate the term) "technical debt" (which in the same paradigm should be called "technical theft" as we all know no-one ever will "repay" it).
