6.小小恶作剧中函数两种不同变量类型的不同引用方式


<body>
	<script>
	function cooking(foodList1){
		foodList1[2] = "rich";
		// console.log(foodList1);
	}

	var foodList = ["fish", "list"];
	cooking(foodList);
	console.log(foodList);


		
	</script>
</body>
</html>
`
执行结果：(3) ["fish", "list", "rich"]
此处foodlist为引用类型，两者相互影响
