I have a Json object coming from localStorage and I need it to be converted to a Long type, in case entidadeId

idEntidade = localStorage.getItem("idEntidade");
var entidadeId = JSON.parse(idEntidade);

" be converted to a Long" - what is a "Long"?

That’s not Java?

@Eduardokrakhecke ok. No Javascript available Long. This string you want to convert has text or only numbers?

Even though Long does not exist, I was curious to know what would be the purpose in converting? I would be very grateful to know :)

@DVD is because the localStorage keeps everything in String.

@DVD is that I am saving a parameter that is an id in localStorage, and at that moment I need to pass it in a request,and the request asks for a Long type, but it is a String in localStorage, so I needed to convert.

I get it. But this Long you got from where, from Java?

@DVD yes, it’s coming from Java.

Since Javascript is not a strongly typed language, I suggest you just convert your variable to a number, as follows:

idEntidade = Number(localStorage.getItem("idEntidade"));
