Repeat structure does not work when my object is copied without reference

Question

I need to remove an attribute from my object (indexvariacaoatributo), but I need it to remain in the root object.

This is my algorithm that receives in variable my object and then I remove the attribute indexvariacaoatributo of the object, in this way works perfectly the algorithm, but in addition to removing the variable variables, it is also removed from the variable categorieForm:

    var variacoes = categoriaForm.variacoes
    if(variacoes[0].estoque_variacao == null || variacoes[0].estoque_variacao == 0){
      variacoes = [];
    }
    //Retira do objeto o indexvariacaoatributo
    for(let i=0;i<variacoes.length;i++){
      for (let j=0;j<variacoes[i].atributo.length;j++){
        console.log(variacoes[i].atributo[j].indexvariacaoatributo);
        delete variacoes[i].atributo[j].indexvariacaoatributo
      }
    }

  console.log(variacoes);

I tried to make an unregistered copy of these forms:

var variacoes = Object.assign({}, categoriaForm.variacoes);

I also tried to:

var variacoes = { ...categoriaForm.variacoes };

But in these two ways, when I print the variable variation I realize that my index is still there. I put on that console.log and I realized it’s not going inside my for.

There is something else that needs to be done when copying an object in this way?

Man not the cutest way but so it works:

var minhaVar = JSON.parse(JSON.stringify(obj));
