Interesting ideas around front-end frameworks:
The common view is that frameworks make it easier to manage the complexity of your code: the framework abstracts away all the fussy implementation details with techniques like virtual DOM diffing. But that’s not really true. At best, frameworks move the complexity around, away from code that you had to write and into code you didn’t.
Instead, the reason that ideas like React are so wildly and deservedly successful is that they make it easier to manage the complexity of your concepts. Frameworks are primarily a tool for structuring your thoughts, not your code.
