Node.js Benchmark

NODE_ENV=production node --prof index.js 会输出isolate日志

node --prof-process isolate-0x102925000-30026-v8.log > processd.txt 解析日志，生成可阅读的格式

node --prof-process --preprocess isolate-0x102925000-30026-v8.log > processd.json 生成json的格式日志，用 v8 里带的 v8/tools/profview/index.html 打开可以解析

	prettier-eslint	eslint-plugin-prettier	eslint-config-prettier
What it is	A JavaScript module exporting a single function.	An ESLint plugin.	An ESLint configuration.
What it does	Runs the code (string) through prettier then eslint --fix. The output is also a string.	Plugins usually contain implementations for additional rules that ESLint will check for. This plugin uses Prettier under the hood and will raise ESLint errors when your code differs from Prettier's expected output.	This config turns off formatting-related rules that might conflict with Prettier, allowing you to use Prettier with other ESLint configs like eslint-config-airbnb.
How to use it	Either calling the function in your code or via [prettier-eslint-cli](https://github.co
