You'r welcome @johnclary. Awesome refactor.

Let me just add a suggestion: I would move this sentence var newPath = path.slice();before the for loop to avoid its execution inside the loop. And using ES6 I'm sure you'll get a much more terse code 👍

thanks @YagoLopez. In my testing, path.slice() needs to stay inside the for loop to make a clean break from other obj references to it. will be trying to scratch out an ES6 refactor of this.

Hey guys! May I recommend you take a look at object-scan. Might be very relevant and exciting 😉 Please do take a look at the source code as well!

Looks great! Thanks for the information

How would I go about making this match a wildcard for the key value? For example, my data is:

'{"answer0":"Legend of Zelda","answer1":"Final Fantasy","answer2":"Animal Crossing","answer3":"The Witcher","answer4":"Kingdom Hearts","answer5":"The Sims","artist0":"Wu-Tang Clan","artist1":"Pet Shop Boys","team_id":"79369254","edition_id":"35889464","answerCount":"6","artistCount":"2"}'

I just want the answer* values . . .

@kyds3k With object-scan you would simply do

const objectScan = require('object-scan');

const data = {
  answer0: 'Legend of Zelda',
  answer1: 'Final Fantasy',
  answer2: 'Animal Crossing',
  answer3: 'The Witcher',
  answer4: 'Kingdom Hearts',
  answer5: 'The Sims',
  artist0: 'Wu-Tang Clan',
  artist1: 'Pet Shop Boys',
  team_id: '79369254',
  edition_id: '35889464',
  answerCount: '6',
  artistCount: '2'
};

console.log(objectScan(['answer*'], { rtn: 'value', reverse: false })(data));
/* => [
  'Legend of Zelda',
  'Final Fantasy',
  'Animal Crossing',
  'The Witcher',
  'Kingdom Hearts',
  'The Sims',
  '6'
] */

console.log(objectScan(['(^answer\\d+$)'], { rtn: 'value', reverse: false })(data));
/* => [
  'Legend of Zelda',
  'Final Fantasy',
  'Animal Crossing',
  'The Witcher',
  'Kingdom Hearts',
  'The Sims'
] */

Awesome @simlu 👍

hi i want to try search something using your object scan can that search not fixed value on this object

const data = { merah: [ { harga: 30000, sku: 'SKU-123asd-asdasd', stok: '20', ukuran: 'XL', warna: 'Merah', _id: '6069895a0e277a332ca19e49', }, { harga: 30000, sku: 'SKU-123asd-asdasda', stok: '20', ukuran: 'L', warna: 'Merah', _id: '606b6ea7ff4a142508df2a98', }, ], hijau: [ { harga: 30000, sku: 'SKU-123asd-asdasds', stok: '20', ukuran: 'XL', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98', }, { harga: 30000, sku: 'SKU-123asd-asdasdsa', stok: '20', ukuran: 'L', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98', }, ], }

the data will not fixed its will be like another color in english or what ever how do i search depend on the first word like "hijau", "merah"

Sure, just use ** as a search needle and filter with filterFn using value. It's all in the docs with detailed examples. Let me know if you're struggling

Or are you trying to search on the key? In that case you could just specify the needle as *? Is that what you're looking for? If you could provide more details with expected output I'd be able to help better

Or are you trying to search on the key? In that case you could just specify the needle as *? Is that what you're looking for? If you could provide more details with expected output I'd be able to help better

yeah i try to search at the key so i should use * instead of ** ? ah yeah is it work on ReactJs too ?

@mzcoder-hub I'd really recommend you take a look at the readme here . It details all the basic use cases and it sound like yours is one of them. Your question is not very clear and so I can't answer it. So you have to options:

1. go to the readme and figure out what you need to know yourself
2. reformulate the question in a way that I can understand (ideally with example results!) and I will do my best to provide a working solution

Thank you, L~

@simlu i have this data https://prnt.sc/115tz4e and the key is not fixed its generate from database, and i want to search keyword example "merah" and i want to retrieve data from array "merah"

Is this what you want?

const objectScan = require('object-scan');

const data = { merah: [{ harga: 30000, sku: 'SKU-123asd-asdasd', stok: '20', ukuran: 'XL', warna: 'Merah', _id: '6069895a0e277a332ca19e49' }, { harga: 30000, sku: 'SKU-123asd-asdasda', stok: '20', ukuran: 'L', warna: 'Merah', _id: '606b6ea7ff4a142508df2a98' }], hijau: [{ harga: 30000, sku: 'SKU-123asd-asdasds', stok: '20', ukuran: 'XL', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }, { harga: 30000, sku: 'SKU-123asd-asdasdsa', stok: '20', ukuran: 'L', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }] };

console.log(objectScan(['*[*]'])(data));
// => [ [ 'hijau', 1 ], [ 'hijau', 0 ], [ 'merah', 1 ], [ 'merah', 0 ] ]

Is this what you want?

const objectScan = require('object-scan');

const data = { merah: [{ harga: 30000, sku: 'SKU-123asd-asdasd', stok: '20', ukuran: 'XL', warna: 'Merah', _id: '6069895a0e277a332ca19e49' }, { harga: 30000, sku: 'SKU-123asd-asdasda', stok: '20', ukuran: 'L', warna: 'Merah', _id: '606b6ea7ff4a142508df2a98' }], hijau: [{ harga: 30000, sku: 'SKU-123asd-asdasds', stok: '20', ukuran: 'XL', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }, { harga: 30000, sku: 'SKU-123asd-asdasdsa', stok: '20', ukuran: 'L', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }] };

console.log(objectScan(['*[*]'])(data));
// => [ [ 'hijau', 1 ], [ 'hijau', 0 ], [ 'merah', 1 ], [ 'merah', 0 ] ]

i want to get data inside of array object

[
    {
      harga: 30000,
      sku: 'SKU-123asd-asdasd',
      stok: '20',
      ukuran: 'XL',
      warna: 'Merah',
      _id: '6069895a0e277a332ca19e49',
    },
    {
      harga: 30000,
      sku: 'SKU-123asd-asdasda',
      stok: '20',
      ukuran: 'L',
      warna: 'Merah',
      _id: '606b6ea7ff4a142508df2a98',
    },
  ],

only single key

if i search 'merah' i only get data from array object from key 'merah'

Still guessing what you want... how about this?

const objectScan = require('object-scan');

const data = { merah: [{ harga: 30000, sku: 'SKU-123asd-asdasd', stok: '20', ukuran: 'XL', warna: 'Merah', _id: '6069895a0e277a332ca19e49' }, { harga: 30000, sku: 'SKU-123asd-asdasda', stok: '20', ukuran: 'L', warna: 'Merah', _id: '606b6ea7ff4a142508df2a98' }], hijau: [{ harga: 30000, sku: 'SKU-123asd-asdasds', stok: '20', ukuran: 'XL', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }, { harga: 30000, sku: 'SKU-123asd-asdasdsa', stok: '20', ukuran: 'L', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }] };

const r = objectScan(['*[*]'], { rtn: 'value' })(data);
console.log(JSON.stringify(r));
// => [{"harga":30000,"sku":"SKU-123asd-asdasdsa","stok":"20","ukuran":"L","warna":"Hijau","_id":"606b6ea7ff4a142508df2a98"},{"harga":30000,"sku":"SKU-123asd-asdasds","stok":"20","ukuran":"XL","warna":"Hijau","_id":"606b6ea7ff4a142508df2a98"},{"harga":30000,"sku":"SKU-123asd-asdasda","stok":"20","ukuran":"L","warna":"Merah","_id":"606b6ea7ff4a142508df2a98"},{"harga":30000,"sku":"SKU-123asd-asdasd","stok":"20","ukuran":"XL","warna":"Merah","_id":"6069895a0e277a332ca19e49"}]

Im fixing it using the script above

console.log(getObjects(js,'','SGML'));

@YagoLopez Thanks! Exactly what I need and it works great
