Good afternoon
How can i use variable when i try to get object from objects here is my array:
let coinsArr = [{
"id": "bitcoin",
"name": "Bitcoin",
"symbol": "BTC",
"checked": true
},
{
"id": "ethereum",
"name": "Ethereum",
"symbol": "ETH",
"checked": true
}]
here is my objects
let coinsObj = {
"BTC": {
"USD": 49220.39
},
"SOL": {
"USD": 186.6
}
to calling to some object i have to do "coinsObj.BTC.USD"
my question is how can i change the "BTC" between coins."to".USD instead of some variable like "coinsObj.coinsArr[0].symbol.USD"
