How I can get an index value of a array inside a another array

Question

I have a array in this format

const Adicionais = [{
  ID: 0,
  Nome: 'Adiocinais Açai',
  MaxOpcoes: 3,
  Itens: [{
    Nome: 'Morango',
    Valor: 5.00,
    ID: 0,
  }, {
    Nome: 'Raspas de Chocolate',
    Valor: 5.00,
    ID: 1,
  }, {
    Nome: 'Biz de Chocolate',
    Valor: 5.00,
    ID: 2,
  }]
}]

I need to get the value of index VALOR inside the array ITENS and SUM the value of all items that I have an ID saved in another array of the items selected. I tried do this that form

const ValorAdicionas = ProdutoAdicionais.filter((item) =>  (item.Itens.filter((a) => (adicionaisChecked.includes(a.ID))).reduce((a, v) => a = a + v.Valor, 0)))

but does not work. The array ProdutosAdicionais have the value of array Adicionais, and the array adicionaisChecked have the ID of array Itens

the expected output is the sum of all indice VALOR of the element ID is inside that array AdicionaisChecked, example i have the ID of Item Banana and Melon, i need the sum of the indice VALOR of these items — Matheus Martins

There is no word "indice" in English. The closest I could think of is the plural of index, indices. But now I'm not sure if maybe you mean "property" or "key"... Please do update your question if either makes more sense. — Heretic Monkey

const adicionaisChecked=[1];
const ProdutoAdicionais = [{
  ID: 0,
  Nome: 'Adiocinais Açai',
  MaxOpcoes: 3,
  Itens: [{
    Nome: 'Morango',
    Valor: 5.00,
    ID: 0,
  }, {
    Nome: 'Raspas de Chocolate',
    Valor: 5.00,
    ID: 1,
  }, {
    Nome: 'Biz de Chocolate',
    Valor: 5.00,
    ID: 2,
  }]
}]


const valorAdicionas = ProdutoAdicionais.reduce((acc,item)=>{
 return acc.concat(item.Itens.filter(a=>adicionaisChecked.includes(a.ID)))
},[]).reduce((a,v)=>a+v.Valor,0);

console.log(valorAdicionas);

I hope this code helping you

const Adicionais = [{
  ID: 0,
  Nome: 'Adiocinais Açai',
  MaxOpcoes: 3,
  Itens: [{
    Nome: 'Morango',
    Valor: 5.00,
    ID: 0,
  }, {
    Nome: 'Raspas de Chocolate',
    Valor: 5.00,
    ID: 1,
  }, {
    Nome: 'Biz de Chocolate',
    Valor: 5.00,
    ID: 2,
  }]
}]
adicionaisChecked = [0,1]
Adicionais.map(o=>o.Itens.filter(v=>adicionaisChecked.indexOf(v.ID) != -1)).map(k=>k.reduce((sum, prev)=>sum + prev.Valor,0))
