📝 Walkthrough

Walkthrough

A new subsection, "Why Not Use JavaScript Classes?", is added to the TanStack Table V9 memory-performance blog article. It explains why ES class single-inheritance is a poor fit for TanStack Table's dynamically composed, feature-driven APIs, contrasting it with the shared-prototype approach and discussing mixin-chain fragility.

"Why Not Use JavaScript Classes?" section src/blog/tanstack-table-v9-memory-performance.md	Adds a new subsection explaining the mismatch between JavaScript's single-inheritance class model and TanStack Table's conditional, feature-driven API composition, and why shared prototypes are preferred over mixin chains.

Poem

🐇 A class said "inherit me, one line!"
But features need to mix and shine.
With prototypes we stack our tricks,
No fragile mixin chains to fix—
Each table gets the APIs it needs,
A dynamic system that succeeds! 🌿
