Syntax

arr.reduce(callbackFunction, [initialValue])

Quid faciam reducere?

Munus est minuere, quae est ordinata in loramenta.

Res peragi potest in ordinata per munus a callback.

Operationes in ordine ad finem, redit in unum redigendum pretii

Minuere posse adhiberi, exempli gratia, est ad totam cart

exemplum

  O lux = [1,2,3,4,5];
  arr.reduce( (Accumulator, currentValue, currentIndex, ordinata) => { 
      //aliqua res;
      redire aliquid,;
  });

 

Et Callback Function

Callback est munus, quod invocatum est enim elementum ad invicem ordinata, in transeuntes 4 Transierunt sunt rationes, quae ad redigendum in munus.

haec 4 tum argumentis potest uti munus in callback.

Quatuor rationes habet

  1. Accumulator – Primum elementum quod ordinata per primam loop ad neque valorem, si suppleverunt. Deinde rediit ad priorem de valore loop.
  2. currentValue – In elementum quod ordinata current. Ab animi secundo elementum quod ordinata per id. Sanctus[1], Cum valorem ratio non Transierunt. Transierunt igitur si sit praesens valorem ratio incipit ab 1 ad elementum ordinata Sanctus[0].
  3. currentIndex – Indicem ex in current elementum.
  4. ordinata – Totam aciem.

Exemplum working

O lux = [1,2,3,4,5];

arr.reduce(
  (Accumulator, currentValue, currentIndex, ordinata) => {
    console.log(Accumulator: (1 De loop, Accumulator est Sanctus[0], ergo est prior rediit ad valorem loop): ${Accumulator}`);
    console.log(currentValue: (Per ansas ordinata, incipiens a Sanctus[1]): ${currentValue}`);
    console.log(currentIndex:: ${currentIndex}`);
    console.log(`ordinata: ${ordinata}`);
    console.log('---');
    reditus Accumulator + currentValue;
  }
);

output

Accumulator (1 De loop, Accumulator est Sanctus[0], ergo est prior rediit ad valorem loop): 1
currentValue (Per ansas ordinata, incipiens a Sanctus[1]): 2
currentIndex: 1
ordinata: 1,2,3,4,5
---
Accumulator (1 De loop, Accumulator est Sanctus[0], ergo est prior rediit ad valorem loop): 3
currentValue (Per ansas ordinata, incipiens a Sanctus[1]): 3
currentIndex: 2
ordinata: 1,2,3,4,5
---
Accumulator (1 De loop, Accumulator est Sanctus[0], ergo est prior rediit ad valorem loop): 6
currentValue (Per ansas ordinata, incipiens a Sanctus[1]): 4
currentIndex: 3
ordinata: 1,2,3,4,5
---
Accumulator (1 De loop, Accumulator est Sanctus[0], ergo est prior rediit ad valorem loop): 10
currentValue (Per ansas ordinata, incipiens a Sanctus[1]): 5
currentIndex: 4
ordinata: 1,2,3,4,5
---

 

Providemus valorem

Secundo ratione parametri (initialValue) ad redigendum initialValue faciam tibi munus erit, sicut in primam loop ad argumentum Accumulator.

Nota quod in current valorem 1 loop iam incipit ad primum elementum quod ordinata

Exemplum working

  O lux = [1,2,3,4,5];

  arr.reduce(
  (Accumulator, currentValue, currentIndex, ordinata) => {
    console.log(Accumulator: ( 1 de loop, id est valorem, reddidit igitur de valore ex prior loop): ${Accumulator}`);
    console.log(currentValue: (Per ansas ordinata, incipiens a Sanctus[0]): ${currentValue}`);
    console.log(currentIndex:: ${currentIndex}`);
    console.log(`ordinata: ${ordinata}`);
    console.log('---');
    reditus Accumulator + currentValue;
  }, 0
);

output

Accumulator ( 1 de loop, id est valorem, reddidit igitur de valore ex prior loop): 0
currentValue (Per ansas ordinata, incipiens a Sanctus[0]): 1
currentIndex: 0
ordinata: 1,2,3,4,5
