this Keyword in Different Contexts

Why will this code fail?

class Example {
  constructor() {
    setTimeout(function() {
      this.method();
    }, 1000);
  }
  
  method() {
    console.log('Method called');
  }
}

setTimeout is used incorrectly
method is not defined
this binding is lost in callback
The code fails due to 'this' binding issues: 1) setTimeout callback creates new 'this' context, 2) Inside callback, 'this' doesn't refer to class instance, 3) Results in 'undefined' or 'window' reference, 4) Common issue with callbacks in classes, 5) Can be fixed with arrow function or bind(), 6) Demonstrates why 'this' handling is crucial in async code.
