clone & cloneDeep(考虑各种对象) _.clone(value)创建一个 value 的浅拷贝。_.cloneDeep(value)创建一个 value 的深拷贝。 注意: 这个方法参考自 structured clone algorithm 以及支持 arrays、array buffers、 booleans、 date objects、maps、 numbers, Object objects, regexes, sets, strings, symbols, 以及 ...
To clone an array of objects in Vue.js, there are different techniques you can use, such as the spread operator, JSON methods, or custom functions. Choosing the right method is important to ensure a deep copy without affecting the original data.
3、在key()或者value()上使用Array.from console.log(Array.from(myMap.keys())); // 输出 ["key1", "key2"] 1. 复制、合并Map对象 复制 复制后不是同一个引用地址 let myMap2 = new Map([[1, 'one']]) console.log(clone.get(1)); // one ...

console.log({} instanceof Object); // true constructor 似乎完全可以应对基本数据类型和引用数据类型 但如果声明了一个构造函数,并且把他的原型指向了 Array 的原型,所以这种情况下,constructor 也显得力不从心 console.log((true).constructor === Boolean); // true ...
