排序方法 : reverse, sort 获取数组索引 : indexOf, lastIndexof, findIndex 遍历方法 : forEach, filter, map, some, every, find, reduce 判断是否是数组 : Array.isArray, instanceof() 扁平化数组 :flat, reduce 接下来一一说明 : 一. 创建数组 1. Array.from 用于将伪数组结构转换为真数组,也就是...
Unfortunately, all of these create shallow copies, not deep ones.Shallow cloning in JavaScript # With a shallow copy, the original array or object is a unique copy, but any arrays or objects contained within it are actually just references to the original....
JSON.stringify()methods, which allow you to convert a JavaScript object to a JSON string and vice versa. You can use these methods to create a deep copy of an array, meaning that the copy contains copies of all the elements in the original array, including any nested arrays or objects....
// Recurse if we're merging plain objects or arrays // 如果要合并纯对象或数组,使用递归 if ( deep && copy && ( jQuery.isPlainObject( copy ) || ( copyIsArray = Array.isArray( copy ) ) ) ) { if ( copyIsArray ) { copyIsArray = false; clone = src && Array.isArray( src ) ?
### 基础概念 在React中,深拷贝(deep copy)指的是创建一个新对象或数组,并将原始对象或数组的所有嵌套属性和元素复制到新对象或数组中。这样,修改新对象或数组不会影响原始对象或数组。 ...

利用结构化拷贝算法。支持拷贝arrays,array buffers,booleans, data objects, maps, numbers,Objectobjects, regexes, sets, strings, symbols, and typed arrays.arguments对象的可枚举属性被拷贝为普通对象。 为不可拷贝的值(如错误对象、函数、DOM节点和弱映射)返回一个空对象。
