util.inspect在不同节点版本上的行为不同

Question

code:

var util = require('util')
var body = '{doc}'
try{
  body = JSON.parse(body)
}catch(err){
  console.log(util.inspect(err))
}

The same code running on different versions giving different results

node 6.xx: (inspect is not working)

SyntaxError: Unexpected token i in JSON at position 1
    at Object.parse (native)

on node 0.xx:

[SyntaxError: Unexpected token i]

PS: I have used depth null, still am getting same results on nodev6

Answer 1

It's not that it's not working, it's just that the util.inspect() implementation changed between the major node versions. Typically it's changes like this that only happen in a new major version, so it probably changed with a new major version (eg 4.0.0, 5.0.0, etc.).
