I have the following JSON:

[{"id": 1,"preco": "R$50"}, {"id": 2,"preco": "R$70"}]

I would like to change the price value by removing the R$ leaving only the numbers using javascript or jQuery

You can use the .map() to do this, an example would be:

const arr = [{"id": 1, "preco": "R$50"}, {"id": 2, "preco": "R$70"}];
const formatado = arr.map(obj => {
  return {
    id: obj.id,
    preco: Number(obj.preco.slice(2))
  };
});

console.log(formatado);

The idea is to use .slice(2) to remove the first two characters of that string, and Number to convert to number. If you want you can still use string, ignoring the Number, depends on how you use these values.
