	// Test string replace with regex

	// Basic regex replacement
	const str1 = 'hello world';
	const re1 = new RegExp('world');
	const result1 = str1.replace(re1, 'universe');
	console.log('Basic replace:', result1);

	// Test with global flag
	const str2 = 'foo bar foo baz';
	const re2 = new RegExp('foo', 'g');
	const result2 = str2.replace(re2, 'qux');
	console.log('Global replace:', result2);

	// Test without global flag (should replace only first)
	const str3 = 'foo bar foo baz';
	const re3 = new RegExp('foo');
	const result3 = str3.replace(re3, 'qux');
	console.log('Non-global replace:', result3);

	// Test with regex pattern (digits)
	const str4 = 'I have 2 apples and 3 oranges';
	const re4 = new RegExp('[0-9]+', 'g');
	const result4 = str4.replace(re4, 'X');
	console.log('Replace digits:', result4);

	// Test with dot pattern
	const str5 = 'abc123def';
	const re5 = new RegExp('...', 'g');
	const result5 = str5.replace(re5, 'X');
	console.log('Replace with dot:', result5);

	// Test string replace (without regex) - should still work
	const str6 = 'hello world';
	const result6 = str6.replace('world', 'there');
	console.log('String replace:', result6);

	console.log('All replace tests passed!');
