Bootcamp for CS not Web Dev.

No bootcamp teaches the level of fundamentals above and I can go into extensive detail how no bootcamp I know of (including Codesmith) teaches these concepts from a fundamentals approach despite what they might say. There is one kind of bootcamp-like program for senior engineers that actually does have like 4 week units on these topics taught but industry legends in those areas but I don't know if they are still operating. Most bootcamps teach the "what" and some bootcamps go deeper to the "how" (e.g. HOW does the event loop work in Javascript). The CS fundamentals above are on the "why" - why is the abstract theoretical patterns/reasoning that get applied to real situations. For example. A bootcamp might teach you what SQL is and the basic syntax of some queries. Going one level deeper, one might teach you how relational databases work in general. Fundamentals approach teach you set theory and how a database can be built on top of this concept. So you arrive at "database" starting from these concepts, instead of starting at the top and drilling deeper. TLDR: I wouldn't trust what bootcamps tell you they are teaching you is what they claim and just because someone says "We are teaching the fundamentals of System Design" that doesn't make it so. Do you know how many burger chains have the "best burger in America"? lol
