Error in JSON.parse() NodeJs about help HOT 7 CLOSED

but I haven't found any doc to describe it.

console.log said it using util.format.

util.format said it using util.inspect for object.

util.inspect is telling you depth is 2 by default.

I'm happy to fix it

Shouldn't it just display issue?
Since REPL or console.log do not like browser provide a way to expend each property, the display of [Object] still means it is a proper object.

https://nodejs.org/api/util.html#utilinspectobject-showhidden-depth-colors
The maximum depth of console.log show is 2.

import pug from 'pug'

const html = pug.render('p= data', {
  data: {
    string: 'example text',
    object: { string: 'text 2', object: { string: 3 } } // not [Object]
  }
})

console.log(html) // <p>[object Object]</p>

pug is actually printing the object using .toString and that is expected result.

It has nothing to do with JSON.parse(), as @climba03003 mentioned it's the documented behavior of console.log(). You should first convert the data to a string with e.g. JSON.stringify(), util.format(), or a third party library.

Sounds reasonable, the default depthofconsole.logis 2, that's why{ string: 3 }` doesn't been shown, but I haven't found any doc to describe it.

In your code, you're correctly stringifying an object and then parsing it back into an object. However, when you pass _data to your Pug template, you're assigning the entire object to a variable called data. This is why you're seeing [object Object] in your view because data is an object, and Pug is displaying it as a string representation.
