I want to intercept Boolean Coercion for Objects in JavaScript

Read Original

The article details the author's attempt to create a custom Boolean-like object in JavaScript that can correctly evaluate to false when coerced. It explains MDN's warnings, tests with Symbol.toPrimitive and valueOf, and concludes that boolean coercion uniquely ignores user-defined methods, ending with a call for help from the ECMAScript community.
