Git 比较不同版本文件差异的常用命令格式：

git diff                                       查看尚未暂存的文件更新了哪些部分

git diff filename 查看尚未暂存的某个文件更新了哪些

git diff –cached                    查看已经暂存起来的文件和上次提交的版本之间的差异

git diff –cached filename 查看已经暂存起来的某个文件和上次提交的版本之间的差异

window.open() not working on safari

因安全机制，window.open在safari 浏览器中屏蔽掉了, 解决办法如下

let newTab = window.open()
setTimeout(() => {
  newTab = 'https://www.baidu.com'
}, 500)
