Nested JSON - Join sub-object

Question

How can I remove sub-objects?

[{
    "id": "1",
    "desc": "SOME PRODUCT",
    "codigo": "CODE-28",
    "codigoBarras": "2000000001",
    "unidade": "PCT",
    "price": "24.15",
    "current_inventory": [{
        "2kg": "5",
        "5kg": "5",
        "10kg": "5",
        "20kg": "5",
        "productId": "1"
     }]
 }]

[{
    "id": "1",
    "desc": "SOME PRODUCT",
    "codigo": "CODE-28",
    "codigoBarras": "2000000001",
    "unidade": "PCT",
    "price": "24.15",
    "current_inventory_2kg": "5",
    "current_inventory_5kg": "5",
    "current_inventory_10kg": "5",
    "current_inventory_20kg": "5",
}]

Answer 1

Use Object.entries and reduce will simplify.

 const data = [ { id: "1", desc: "SOME PRODUCT", codigo: "CODE-28", codigoBarras: "2000000001", unidade: "PCT", price: "24.15", current_inventory: [ { "2kg": 5, "5kg": 5, "10kg": 5, "20kg": 5, productId: 1 } ] } ]; const [first] = data; const updated = Object.entries(first).reduce((acc, [key, value]) => { if (Array.isArray(value)) { value.forEach(item => Object.entries(item).forEach( ([cKey, cValue]) => (acc[`${key}_${cKey}`] = cValue) ) ); } else { acc[key] = value; } return acc; }, {}); console.log(updated);

Answer 2

Use Object.keys() and a forEach loop

 var x =[ { "id": "1", "desc": "SOME PRODUCT", "codigo": "CODE-28", "codigoBarras": "2000000001", "unidade": "PCT", "price": "24.15", "current_inventory": [ { "2kg": "5", "5kg": "5", "10kg": "5", "20kg": "5", "productId": "1" } ] } ] x[0].current_inventory.forEach(e=>{ Object.keys(e).forEach(j=>{ x[0]['current_inventory_'+j]=e[j]; }) delete x[0].current_inventory }) console.log(x)

THANK YOU VERY MUCH!!!

Solved using the code below:

data is de object

estoqueFracionado is the sub-object

              for (let [key, value] of Object.entries(data)) {
                    value.estoqueFracionado.forEach (e => {
                        Object.keys(e).forEach(j => {
                            value['estoqueFracionado_' + j] = e[j]
                        })
                        delete value.estoqueFracionado
                    })
                }
