Well, I'm developing an app with ionic 3. As I try to write some data to the array, "\ n" appears at the beginning and at the end of the array. Here is the code:

 element = this.pedido.produto;

if (this.vetCarrinhoAux.indexOf(element) === -1) {
  this.vetCarrinho.push(element);

  localStorage.setItem("vetor", JSON.stringify(this.vetCarrinho));

In LocalStorage, it looks like this:

[\n celular \n]

localstorage array ionic ionic2 ionic3

You can use .trim()

element = this.pedido.produto;

if (this.vetCarrinhoAux.indexOf(element) === -1) {
  this.vetCarrinho.push(element);

  localStorage.setItem("vetor", JSON.stringify(this.vetCarrinho.trim()));
