Benchmark: flatmap vs reduce t

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

/*your preparation JavaScript code goes here
To execute async code during the script preparation, wrap it as function globalMeasureThatScriptPrepareFunction, example:*/
let a = Array.from({
        length: 10000
    },
    (v, i) => ({
        name: i,
        station: Array.from({
                length: 20
            },
            (v2, i2) => i2)
    })
)

Tests:

flatmap
/*When writing async/deferred tests, use `deferred.resolve()` to mark test as done*/ a.flatMap((l) => l.station.map(s=>({line:l.name,station:s})))
reduce
a.reduce((acc,curr) => (curr.station.map(s=>acc.push({line:curr.name,station:s})),acc),[])
