Here I want to find the minimum bidAmount, but after checking below condition,
I tried to do like this.
let minimum = event.reduce(function(prev, curr) {
return prev.bidAmount < curr.bidAmount ? prev : curr;
});
But and tried to add my condition also. But doesn't work well.
I want just the minimum bidAmount (skip for vendorBidId is null) only.
Math.min on a Filter and map
let event = [{ "vendorBidId": 58, "participantName": "bro.gee@test.in", "bidAmount": 10000, "productionRate": 10000, "bidTime": "2021-10-21T14:55:05.957324", "isYou": false, "awarded": false }, { "vendorBidId": 57, "participantName": "test@gmail.com", "bidAmount": 20000, "productionRate": 20000, "bidTime": "2021-10-21T14:50:24.493522", "isYou": false, "awarded": true }, { "vendorBidId": null, "participantName": "bro+2@test.com", "bidAmount": 0, "productionRate": null, "bidTime": null, "isYou": false, "awarded": false }, { "vendorBidId": null, "participantName": "bro.hey@test.com", "bidAmount": 0, "productionRate": null, "bidTime": null, "isYou": true, "awarded": false } ]
const min = Math.min(...event
.filter(evt => evt.vendorBidId)
.map(({bidAmount}) => bidAmount)
);
console.log(min)Using reduce is a simple approach (if you want the entire object).
If you just need the minimum vakue, you can use Math.min after mapping the minAmount key values.
