Explains exactly which coercions happen, why null == undefined but null >= 0 behaves differently, and where the 22‑step abstract equality algorithm applies; shows the surprising edge cases that break intuitive rules and demonstrates a practical JavaScript equality table that maps == and === outcomes. Recommends concrete tools — parseInt/Number/toString, the console, and explicit casts — and claims === avoids coercion while == runs the full algorithm, so it’s worth watching if specific rules and examples matter.
