The other day, I saw someone on Twitter say (I’m not linking to the original tweet because I don’t want to pile-on the author):
I don’t bother with frameworks, I just use vanilla JS.
I’m smarter than the thousands of people who tried to solve the problems I’m about to solve. I’m an expert on security, a11y, browser support, and perf. I don’t care about ROI, I just want to code.
Here’s the thing: frameworks don’t really help you with this stuff.
Earlier this year, WebAIM conducted a survey of the top million sites on the web and found those that use frameworks are actually more likely to have accessibility issues.
I’m not anti-framework, but I am pro-informed-developer. If security, accessibility, performance, and browser support are things you care about – and they absolutely should be – then you need to know the impact that the tools you choose have upon those things. It’s easy to learn the impact that vanilla JS has on them, but it’s harder to understand exactly what impact a framework might have or how that impact might be affected by interactions between it and all of the other frameworks and libraries you mix-in. And many developers don’t bother to learn.
Use frameworks if they’re the right tool for your job. But you should work towards understanding your tools. Incidentally: in doing so, you’ll probably come to discover that frameworks are the right tool for fewer jobs than you thought.
