Repeat structure to replace the value of one array to another

Question

I have the array this.produtoAlvoAlterar.variacao.preco_variacao

I need to replace the variable tag of this array with the value contained in the array this.anuncioAlterar.variations.specifications.preco

I tried to make a repeat structure to pass these values from one array to another, it was like this:

  for(let i=0;i<this.produtoAlvoAlterar.variacao.length;i++){
    for(let j=0;j<this.anuncioAlterar.variations.length;j++){
      for(let k=0;k<this.anuncioAlterar.variations[j].specifications.length;k++){
        if(this.anuncioAlterar.variations[j].specifications[k].key == "Preço"){
          this.produtoAlvoAlterar.variacao[i].preco_variacao = this.anuncioAlterar.variations[j].specifications[k].value;
        }
      }
    }
  }

At the first position of the array the value of this.produtoAlvoAlterar.variacao.preco_variacao should be set to the value "222.22" and in the second position to "333.33" but both positions are having the value "333.33", which is the value of the second key of the array this.anuncioAlterar.variations.specifications

@Edit:

Answer 1

Try to use this code. In the code it goes through all this.produtoAlvoAlterar.variacao and this.anuncioAlterar.variations, he gets the Preço of each anuncioAlterar and settar no produtoAlvoAlterar.

this.produtoAlvoAlterar.variacao.forEach(variacao => {
      this.anuncioAlterar.variations.forEach(anuncioVariacao => {
        let novoPreco = anuncioVariacao.specifications.filter(
            chaveValor => {
              return chaveValor.key === 'Preço';
          });

        variacao.preco_variacao = novoPreco;
      })
    });
