	// Based on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode

	// Non-strict code
	let globalVar = 10;

	// Function with strict mode
	function strictFunction() {

	console.log("Accessing outer scope:", globalVar);

	// Non-strict function - should allow undeclared vars (though not recommended)
	function nonStrictFunction() {
	// Note: In this implementation, undeclared vars might still error
	// as they create implicit globals which is generally an error
	console.log("PASS: Non-strict function executed");
