i need to concat all the 'externalId'(inside prod obj) + "id" (inside sup array) + "name" (inside product obj). What would be the best way to do that? I've tried with map and reduce but I wasn't successful. Any help will be appreciated.
const jsonResultKeys = ['AAA', 'BBB', 'CCC']
const items = [];
jsonResultKeys.forEach(k => {
const item = Jsonresult.items[k];
items.push({
description: item.product.name + ':' + item.product.sup[0] + ':'+ item.product.sup[0].prod.externalId ,
})
});
the output expected for this example:
[
{ description: '4444:2:product1'},
{ description: '3333:2:product2'},
{ description: '2222:1:product3'}
]
the json object:
const Jsonresult = {
items: {
'AAA': {
createdAt: '2021-02-11T17:25:22.960-03:00',
product: {
sup: [{
prod: {
externalId: **4444**
},
id: **2**
}],
name: "**product 1**"
},
total: 9.84,
quantity: 1,
price: 15,
updatedAt: '2021-02-11T17:25:22.960-03:00'
},
'BBB': {
createdAt: '2021-02-11T17:25:22.960-03:00',
product: {
sup: [{
prod: {
externalId: **3333**
},
id: **2**
}],
name: "**product 2**"
},
total: 9.84,
quantity: 1,
price: 15,
updatedAt: '2021-02-11T17:25:22.960-03:00'
},
'CCC': {
createdAt: '2021-02-11T17:25:22.960-03:00',
product: {
sup: [{
prod: {
externalId: **2222**
},
id: **1**
}],
name: "**product 3**"
},
}
},
}
The Array#map() method is the most logical method to use - see @MichaelMano's solution - but if you have to use .push() to populate items (const) then stick with .forEach() as follows:
Object.values( Jsonresult.items ).forEach(item => {
items.push( {description: `${item.product.sup[0].prod.externalId}:${item.product.sup[0].id}:${item.product.name}`} );
});
DEMO
const items = [];
const Jsonresult = {
items: {
'AAA': {
createdAt: '2021-02-11T17:25:22.960-03:00',
product: {
sup: [{
prod: {
externalId: 4444
},
id: 2
}],
name: "product 1"
},
total: 9.84,
quantity: 1,
price: 15,
updatedAt: '2021-02-11T17:25:22.960-03:00'
},
'BBB': {
createdAt: '2021-02-11T17:25:22.960-03:00',
product: {
sup: [{
prod: {
externalId: 3333
},
id: 2
}],
name: "product 2"
},
total: 9.84,
quantity: 1,
price: 15,
updatedAt: '2021-02-11T17:25:22.960-03:00'
},
'CCC': {
createdAt: '2021-02-11T17:25:22.960-03:00',
product: {
sup: [{
prod: {
externalId: 2222
},
id: 1
}],
name: "product 3"
},
}
},
};
Object.values( Jsonresult.items ).forEach(item => {
items.push( {description: `${item.product.sup[0].prod.externalId}:${item.product.sup[0].id}:${item.product.name}`} );
});
console.log( items );You could do the following, Map over the results and return an object, this will create an array of objects.
You wont even need the keys.
const map = Object.values(Jsonresult.items).map((item) => {
return {
description: `${item.product.sup[0].prod.externalId}:${item.product.sup[0].id}:${item.product.name}`,
};
});
[
{ description: '4444:2:product 1' },
{ description: '3333:2:product 2' },
{ description: '2222:1:product 3' }
]
