I credit my web programming abilities to my time spent writing C and assembly in my early hobby years, doing web development during the browser wars, and learning about design patterns from the Gang of Four.

Today I write Typescript in large-scale React applications, but it's backed by the experience of working with low-level memory allocation and algorithmic complexity; needing to write multiple ways of doing the same thing; and having to manually track lots of code without autocomplete. It's not that I have to do all of that anymore, but it built muscle that just can't be built going to bootcamps.
