String value from mongoose document weird behaviour adding in a variable - node.js

Question

I have a mongo document called New which has a sub document called hashtags which has th value name which is a string. I am trying to add all the hashtags belongs to a new in a variable but is adding extra characters (seems that the name string value is not well decoded from the bson or something like that).
New document:
var newSchema = new Schema({
...
hashtags: [{
type : mongoose.Schema.ObjectId,
ref: 'Hashtag'
}]
});
Hashtag document:
var mongoose = require('mongoose')
var Schema = mongoose.Schema
var hashtagSchema = new Schema({
color: {
type: String,
default: '#000000'
},
name: {
type: String
}
});
var hashtag = mongoose.model('Hashtag', hashtagSchema )
module.exports = hashtag
Snniped testing code:
docs.forEach(noticia => {
if(noticia.hashtags.length > 0){
for(i in noticia.hashtags){
if(noticia.hashtags[i] && noticia.hashtags[i].name){
text += '#' + noticia.hashtags[i].name.replace(/\s/g,'') + ' '
}
}
}
})
console.log(text)
Console output:
#Lula #toBSON #_cast #_markModified #_registerAtomic #$__getAtomics #hasAtomics #_mapCast #push #nonAtomicPush #$pop #pop #$shift #shift #pull #splice #unshift #sort #addToSet #set #toObject #inspect #indexOf #pull
I have tried to apply noticia.hashtags[i].name.replace(/\s/g,'').toString() :
docs.forEach(noticia => {
if(noticia.hashtags.length > 0){
for(i in noticia.hashtags){
if(noticia.hashtags[i] && noticia.hashtags[i].name){
text += noticia.hashtags[i].name.toString() + ' '
}
}
}
})
Console output

How I have to decode this string value?

Answer 1

The for...in statement iterates over all non-Symbol, enumerable properties of an object.
var string1 = "";
var object1 = {a: 1, b: 2, c: 3};
for (var property1 in object1) {
string1 += object1[property1];
}
console.log(string1);
// expected output: "123"
You are iterating over the properties of noticia.hashtags
