如果你不完全确认自己是否需要使用代码格式化工具，或者你不确切知道如
何配置代码格式化工具，请花点儿时间在
Prettier playground
（
https://oreil.
ly/TKam1
）中试用一下，探索用法。
ESLint
等
lint
工具和
Prettier
等格式化工具，在功能上有一些重叠。然而，这两类
工具的目的不同，是互补的。如果你同时使用
ESLint
和
Prettier
，应该让
ESLint
专
注于捕获有疑问的编程实践，不要实施格式化规定，约定缩进、引号和空格的用
法。幸好，这并不难。只需在
ESLint
的配置文件中添加一个规则即可禁用可能与
Prettier
冲突的设置。最简单的方法是把
eslint-config-prettier
包添加到项目中。
$ npm install --save-dev eslint-config-prettier
最后，要把
prettier
添加到
.eslintrc.json
文件的
extends
部分中。
extends
部分的
值是一个列表，放在一对中括号内，
prettier
应该放到最后。下面是一个示例。
{
"env":
{
"browser": true
,
"es2021": true
},
"extends":
["eslint:recommended", "prettier"],
"parserOptions":
{
"ecmaVersion":
12,
"sourceType":
