一 、 数组乱序排列

JS 代码如下：

<script src="./lodash.html"></script> <script> var a = [1, 2, 3, 4, 5, 6, 7] var b = _.shuffle(a) console.log(b); </script>

二 、浅拷贝 、深拷贝

var objects = [{ 'a': 1 }, { 'b': 2 }]; var shallow = _.clone(objects); console.log(shallow[0] === objects[0]); // => true var objects = [{ 'a': 1 }, { 'b': 2 }]; var deep = _.cloneDeep(objects); console.log(deep[0] === objects[0]); // => false
