help please with converting array to JSON object
var array = [1, 2, 3, 4];
var arrayToString = JSON.stringify(Object.assign({}, array));
var stringToJsonObject = JSON.parse(arrayToString);
console.log(stringToJsonObject);
I try this and get:
{0: 1, 1: 2, 2: 3, 3: 4}
Expected result
{place0: 1, place1: 2, place2: 3, place3: 4}
You can do this with .reduce:
var array = [1, 2, 3, 4];
var res = array.reduce((acc,item,index) => {
acc[`place${index}`] = item;
return acc;
}, {});
console.log(res);
var array = [1, 2, 3, 4];
const jsonObj = {}
array.forEach((v,i) => jsonObj['place'+i] = v);
console.log(jsonObj)You can use Object.entries() to get all the array elements as a sequence of keys and values, then use map() to concatenate the keys with place, then finally use Object.fromEntries() to turn that array back into an object.
There's no need to use JSON in the middle.
var array = [1, 2, 3, 4];
var object = Object.fromEntries(Object.entries(array).map(([key, value]) => ['place' + key, value]));
console.log(object);
Using for of loop and accumulating into the object
var array = [1, 2, 3, 4];
const result = {}
for (let item of array) {
result['place' + item] = item;
}
console.log(result)
