How can I concatenate this json to obtain it:
complements = ["XYZ 3, CDE TR, AAA 5", "", "NDP 3, DDD FR"] ?
Each address can contain a set of complements which must be concatenated and separated by a comma.
P.s: I'm using javascript. P.s2: Complements can be null like in the second group in JSON.
[
{
"postalcode": "1234",
"street": "ABC",
"number": "1",
"complement": [
{
"type": "B",
"name": "XYZ",
"description": "3"
},
{
"type": "C",
"name": "CDE",
"description": "TR"
},
{
"type": "D",
"name": "AAA",
"description": "5"
}
]
},
{
"postalcode": "444",
"street": "No complements",
"number": "5"
},
{
"postalcode": "2222",
"street": "BBB",
"number": "2",
"complement": [
{
"type": "E",
"name": "NDP",
"description": "3"
},
{
"type": "F",
"name": "DDD",
"description": "FR"
}
]
}
];
My code I'm getting this.complementsList.forEach is not a function.
getComplement(addressesResponse){
this.complementsList = JSON.parse(addressesResponse);
this.complementsList.forEach((item) => {
Object.defineProperty(item, 'complements', {
get: function() {
return this.complement.map((c) => `${c.name} ${c.description}`).join(', '); }
})
});

Having a javascript object, you can go through the keys of the object and combine some of them into strings
It will look something like this:
const jsonObject = [{...}, {...}, ...]
const complements = [];
jsonObject.forEach((item) => {
let complement = item['complement'].reduce((result, currObj)
=> result += (currObj.name+' '+currObj.description), "");
complements.push(complement);
});
This is just an example. There are many ways to do it.
how i solved it :
arr.map((x)=>x.complement != null? (x.complement.map((y)=>y.name+' '+y.description)+"") :'');
