how can i call getwallet function and filter list which has balance more than 0 [closed]
Data is in nested object format which i am getting from an api and the data format is { "info": { "makerCommission": "10", "takerCommission": "10", "buyerCommission": "0", "sellerCommission": "0", "canTrade": true, "canWithdraw": true, "canDeposit": true, "updateTime": "1639767562245", "accountType": "SPOT", "balances": [ { "asset": "BTC", "free": 0.00000371, "locked": 0.00000000 }, { "asset": "LTC", "free": 0.00000769, "locked": 0.00000000 } }
Passing a value info.balances in a function but it is giving an error. i can use object('info.balances') directly and access its data but i want to filter the data so i can get only those value which are greater than 0.

You are not returning anything from your getWalletJSON function. The return statement that you do have belongs to the filter function.
function getWalletJSON(data) {
console.log(46, data);
let arr = data.filter(function(elem) {
console.log((elem.free > 0));
return (elem.free > 0)
});
return arr;
}
