Array filter and map at the same time?

Question

I feel like an idiot, but I need to filter my array, and then map those values, but thats O(2N) and it would make more sense to do it all in O(N) but I can't find a stock Array.prototype function

array.filter(item => !!item.revenue).map(item => item.revenue)

I can always write my own method but it would be best to use the performance optimized Array.prototype ones, if there is one

Answer 1

How about Array.prototype.reduce()?

arr.reduce((newArr, item) => {
    if (!!item.revenue) {
        newArr.push(item.revenue)
    }
    return newArr
}, []);
