3 Gripes With React

I started using React 3.5 years ago, and I still love it. It was such a well-designed solution that not much has changed since then, only superficial stuff like naming. What I learned then is still wholly applicable today because it's such a good idea (although now you can choose from many other libraries). On top of that, we now benefit from an entirely new architecture (fiber) without changing much.

Thanks everyone for participating in the quiz!
Many of you have posted correct answers.

What we know:

A top-level App component returns <Button /> from its render() method.

Question:

>What is the relationship between `` and this in that `Button`’s `render()`?

Recently CSS has got a lot of negativity. But I would like to defend it and show, that with good naming convention CSS works pretty well.

My 3 developers team has just developed React.js application with 7668 lines of CSS (and just 2 !important). During one year of development we had 0 issues with CSS. No refactoring typos, no style leaks, no performance problems, possibly, it is the most stable part of our application.

Here are main principles we use to write CSS for modern (IE11+) browsers:

• SUIT CSS naming conventions + SUIT CSS design principles;
• PostCSS + CSSNext. Future CSS syntax like variables, nesting, and autoprefixer are good enough;
• Flexbox is awesome. No need for grid framework;
• Normalize.css, base styles and variables are solid foundation for all components;
