Disallows .bind(), .call(), and .apply() on callable receivers. When TypeScript type services are available the rule confirms the receiver is a Function via the type checker before reporting. Refactor to use arrow functions or pass arguments directly.

Fixable: No · Options: No · Suggested severity: error

✗ Incorrect

fn.call(thisArg, arg1);
fn.apply(thisArg, args);
const bound = fn.bind(thisArg);

class MyClass {
  run() { setTimeout(this.handler.bind(this), 100); }
  handler() { /* ... */ }
}

✓ Correct

// Call directly — no binding needed
fn(arg1);

// Arrow function preserves lexical this
class MyClass {
  run() { setTimeout(() => { this.handler(); }, 100); }
  handler() { /* ... */ }
}
