The weird things about React
summary
Covers concrete surprises: Strict Mode double-render and effects running twice with a demoable fix, conditional rendering quirks in JSX, forwardRef and “dozens of ways to create refs,” render props surviving to today, act/test pitfalls, non-extendable classes and SuspenseList still vaporware. Shows a TypeScript codemod around props-with-children and describes a published npm tool react-reduce-stress that detects strict mode and pops a helpful warning. Includes a console-patch prank proof-of-concept and notes one real warning was reported and fixed.
