第三方包_json parse better errors - dkvirus/npm-resource-read GitHub Wiki
使用 JSON.parse() 如果出错会打印错误信息，json-parse-better-errors 号称打印更有用的错误信息，just this!!
使用 JSON.parse() 出错打印的报错信息：
JSON.parse('garbage')
/**
undefined:1
garbage
^
SyntaxError: Unexpected token g in JSON at position 0
at JSON.parse (<anonymous>)
at Object.<anonymous> (/Users/dkvirus/Documents/npm-test/test/json-parse-better-errors.js:4:6)
at Module._compile (module.js:652:30)
at Object.Module._extensions..js (module.js:663:10)
at Module.load (module.js:565:32)

at Function.Module.runMain (module.js:693:10)
at startup (bootstrap_node.js:191:16)
at bootstrap_node.js:612:3
*/
使用 json-parse-better-errors 打印的错误信息：（使用前先安装：npm install json-parse-better-errors）
const parseJson = require('json-parse-better-errors')
parseJson('garbage') // more useful error message
/**

恕在下眼拙，并没有看出什么有价值的错误信息。
