Benchmark: FilterMap perf2 - MeasureThat.net

Script Preparation code:

var ingredientsPerServing = Array(10_000).fill().map(() => {
  let o = {
    details: Math.random().toString(),
  }
  if (Math.random() > 0.5) o.measurement = {
    amount: Math.random(),
    unit: Math.random().toString(),
  }
  return o
})

Tests:

Filter Map
ingredientsPerServing .filter((ingredient) => { return ingredient.measurement; }) .map((ingredient) => { return { amount: ingredient.measurement.amount, details: ingredient.details, unit: ingredient.measurement.unit, }; }).length
FlatMap
ingredientsPerServing .flatMap((ingredient) => { return !ingredient.measurement ? [] : [{ amount: ingredient.measurement.amount, details: ingredient.details, unit: ingredient.measurement.unit, }]; }).length
Reduce
ingredientsPerServing .reduce((a, ingredient) => { return !ingredient.measurement ? a : [...a, { amount: ingredient.measurement.amount, details: ingredient.details, unit: ingredient.measurement.unit, }]; }, []).length
Push
ingredientsPerServing .reduce((a, ingredient) => { if (ingredient.measurement) a.push({ amount: ingredient.measurement.amount, details: ingredient.details, unit: ingredient.measurement.unit, }); return a; }, []).length
Boolean
ingredientsPerServing .map((ingredient) => { return ingredient.measurement && { amount: ingredient.measurement.amount, details: ingredient.details, unit: ingredient.measurement.unit, }; }) .filter(Boolean).length
Trutry
ingredientsPerServing .map((ingredient) => { return ingredient.measurement && { amount: ingredient.measurement.amount, details: ingredient.details, unit: ingredient.measurement.unit, }; }) .filter(e => e).length
