1`驼峰转连字符

export function camelToHyphen(str) {
  if (typeof str === 'string') {
    return str.replace(/([a-z])([A-Z])/g, '$1-$2').toLowerCase();
  } else {
    throw 'str must be string'
  }
}

2`连字符转驼峰

export function hyphenToCamel(str) {
  if(typeof str === 'string') {
    return str.replace(/(\-)(\w)/g, function(match, p1, p2) {
      return p2.toUpperCase();
    })
  } else {
    throw 'str must be string'
  }
}

3` 深度克隆

import { isArray, isObject } from "xxx";
//  检测数组， 对象的方法， 自行拟定
export function deepClone(args) {
  let res;
  if(isArray(args)) {
    res = [];
    for(let i = 0; i < args.length; i++) {
      res.push(deepClone(args[i]))
    }
    return res;
  } else if(isObject(args)) {
    res = {};
    for(let key in args) {
      if(args.hasOwnProperty(key)) {
        res[key] = deepClone(args[key])
      }
    }
    return res;
  } else {
    return args;
  }
}
