Javascript中使用Lodash工具库的cloneDeep函数实现深拷贝

<script src="lodash.js"></script>

$ npm i -g npm
$ npm i --save lodash

// Load the full build.
var _ = require('lodash');
// Load the core build.
var _ = require('lodash/core');
// Load the FP build for immutable auto-curried iteratee-first data-last methods.
var fp = require('lodash/fp');
 
// Load method categories.
var array = require('lodash/array');
var object = require('lodash/fp/object');
 
// Cherry-pick methods for smaller browserify/rollup/webpack bundles.
var at = require('lodash/at');
var curryN = require('lodash/fp/curryN');

_.cloneDeep(value)

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