从ahooks里面抽取的一些在rn项目里可以使用的hooks。提高开发效率

import { __read } from '../_virtual/_tslib.js';
import { useState } from 'react';
import useMemoizedFn from '../useMemoizedFn/index.js';

/**
 * 一个可以管理 Map 类型状态的 Hook。
 * @param initialValue 初始值
 * @returns
 */
function useMap(initialValue) {

    var _a = __read(useState(getInitValue), 2), map = _a[0], setMap = _a[1];
    var set = function (key, entry) {
        setMap(function (prev) {
            var temp = new Map(prev);
            temp.set(key, entry);
