//example of grabbing objects that match some key and value in JSON
console.log(getObjects(js,'ID','SGML'));
//returns 1 object where a key names ID has the value SGML

//example of grabbing objects that match some key in JSON
console.log(getObjects(js,'ID',''));
//returns 2 objects since keys with name ID are found in 2 objects

//example of grabbing obejcts that match some value in JSON
console.log(getObjects(js,'','SGML'));
//returns 2 object since 2 obects have keys with the value SGML

//example of grabbing objects that match some key in JSON
console.log(getObjects(js,'ID',''));
//returns 2 objects since keys with name ID are found in 2 objects

//example of grabbing values from any key passed in JSON
console.log(getValues(js,'ID'));

//returns array ["ID", "SortAs", "Acronym", "str"] 

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

@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~

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 ] ]

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"}]

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