store my fetched data to my array const = players - ajax

Question

newbie here. My target is to store my fetched data in my array. T
This is my script. This script function is to join 2 data in 1 if they have the same level. For example player 1 has level 1, player 6 has level 1 also, which means that Player 1 and player 6 will be joined in 1 array. This current script is static, it is not dynamic yet. My target is to store my fetched data here rather than the static ones. Thank you in advance, any help will be appreciated.
const players = [
{
id: 1,
name: 'player1',
level: '1',
},
{
id: 2,
name: 'player2',
level: '2',
},
{
id: 3,
name: 'player3',
level: '3',
},
{
id: 4,
name: 'player4',
level: '3',
},
{
id: 5,
name: 'player5',
level: '2',
},
{
id: 6,
name: 'player6',
level: '1',
}
];
const matching = (list, keyGetter) => {
let mapping = {};
const map = new Map();
list.forEach((item) => {
const key = keyGetter(item);
const collection = map.get(key);
if (!collection) {
map.set(key, [item]);
} else {
collection.push(item);
}
});
Array.from(map).map(([key, value]) => Object.assign(mapping, { [key]: value }));
return mapping
}
const result = matching(players, ({ level}) => { return level});
console.log("RESULT", result);
this is the result of the above script
In this function, this is how i fetch my data. My target is to store my fetched data to the array i made above const = players
