JS 深度拷贝封装方法
JS深度拷贝封装方法：
/*** This is just a simple version of deep copy* Has a lot of edge cases bug* If you want to use a perfect deep copy, use lodash's _.cloneDeep* @param {Object} source* @returns {Object}*/
export function deepClone(source) {if (!source && typeof source !== 'object') {throw new Error('error arguments', 'deepClone')}const targetObj = source.constructor === Array ? [] : {}Object.keys(source).forEach(keys => {if (source[keys] && typeof source[keys] === 'object') {targetObj[keys] = deepClone(source[keys])} else {targetObj[keys] = source[keys]}})return targetObj
}
