理解 redux 的middleware 中间件机制： https://redux.js.org/advanced/middleware

假如对 store.dispatch 函数，做一些调整，比如 log、errorCatch 的事情，通常我们会想到 monkey-patch：

function addLog(store){
	var next = store.dispatch;

	store.dispatch = function(action){
		console.log('action before');


    <meta http-equiv="cache-control" content="max-age=0" />
    <meta http-equiv="expires" content="0" />
    <meta name="renderer" content="webkit"/> 
    <meta http-equiv="Cache-control" content="no-cache">
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no"/>

Depth-First Traversal

function clone(src){
	var dest = src;
	if(!src) {

	} else {
		if(typeof src === 'object') {
			if(Array.isArray(src)) {
				dest = []

	# first:
	lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom \| while read f; do sudo rm /usr/local/${f}; done
	sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*

	# To recap, the best way (I've found) to completely uninstall node + npm is to do the following:

	# go to /usr/local/lib and delete any node and node_modules
	cd /usr/local/lib
	sudo rm -rf node*

	function isThenable(obj){
	if(obj && typeof obj.then === 'function'){
	return true;

	function ChainedPromise(promise, rv, rj){
	this.success = [rv];
	this.fail = [rj];
	this.promise = promise;

	npm publish 发布 npm 包
	1. 默认情况下，不存在 .npmignore，npm 会依据 .gitignore 来选择过滤上传的文件；
	2. 如果存在 .npmignore （即便是空白的），则不再使用 .gitignore;
	3. package.json 里面的 files 字段，拥有较高权重，控制打包的文件。

	默认被排除在外的文件：
	.*.swp
	._*
	.DS_Store
	.git
