Frameworks are handy for — you know — framing. They’re a helpful scaffold provided your project aligns with their model. This applies to UI framework, app frameworks, whatever.

Why do these not “accelerate your work”? Maybe because you’re taking work that’s differently shaped. Maybe original, custom styling is an important part of what you’re selling. That’s great.

But it’s not nearly true for everybody. And so a lot of people use frameworks like this to get the styling where it needs to be, so that they can focus on whatever other thing they’re really selling.
