I want to sort this array in ascending order(bidAmount), and if the vendorBidId is null don't sort keep in the bottom.
I tried like this
array.sort((a,b) => parseFloat(a.bidAmount) - parseFloat(b.bidAmount)).map((ele) => console.log(ele.bidAmount))
I'm need an out like 30,40,50,131,0,0, but for the my above code it will just sort only. I tried with reduce but that does't work properly
array.sort((a,b) => {
const n = a.vendorBidId === null ? Number.MAX_VALUE : a.bidAmount;
const m = b.vendorBidId === null ? Number.MAX_VALUE : b.bidAmount;
return n - m;
});
// "2.5" + "3.5" = "2.53.5"
// "2.5" - "3.5" = -1
Building on what DragatS has shared.. just map through the result of the sort() like this to get the result of [30,40,50,131,0,0]
const res = array
.sort((a, b) => {
const n = a.vendorBidId === null ? Number.MAX_VALUE : a.bidAmount;
const m = b.vendorBidId === null ? Number.MAX_VALUE : b.bidAmount;
return n - m;
})
.map(item => item.bidAmount);
console.log(res);
