Consider that your question already exists here and here and here

Here are some ways to do it:

var atual = 8.66;

//Formato com R$
var f = atual.toLocaleString('pt-br',{style: 'currency', currency: 'BRL'});

//Formato sem R$
var f2 = atual.toLocaleString('pt-br', {minimumFractionDigits: 2});

console.log(f);
console.log(f2);
