JavaScript objects support descriptor-level control, computed accessors, explicit prototype creation, and different ways to check for properties.
Property descriptors, getters and setters, Object.create, hasOwnProperty, and the in operator
These patterns solve different problems: recursion for self-referential logic, memoization for caching, currying for partial application, and debounce or throttle for rate control.

Refs are an escape hatch for imperative cases, and `forwardRef` lets a parent pass a ref through a component boundary intentionally.

Some class lifecycle methods exist for optimization, derived state, or pre-commit DOM reads, and hooks do not map one-to-one with every lifecycle scenario.
shouldComponentUpdate, getDerivedStateFromProps, getSnapshotBeforeUpdate, and hooks vs lifecycle coverage
These hooks and helpers solve timing, refs, deferred rendering, and stable identity concerns that basic hooks do not cover.
