Benchmark: reduce vs flatMap, conditional

Script Preparation code:

var xs = [{
    text: "a",
    sort: false
}, {
    text: "b",
    sort: true
}, {
    text: "c",
    sort: false
}, {
    text: "d",
    sort: true
}, {
    text: "e",
    sort: false
}]

Tests:

reduce
xs.reduce((acc, x) => { if (x.sort) { acc.push(x.text); } return acc; }, ["z"])
flatMap
xs.flatMap((x) => x.sort ? [x.text] : []);
