Organize object array according to one of its attributes

Question

Well, it’s like the title said, I wonder if there’s any way I could arrange a array of objects of increasing shape according to the value of an attribute given to it.

Example:

var objetos = []

var objeto1 {id:gerarId(), nome: nome1, idade: idade1}

var objeto2 {id:gerarId(), nome: nome2, idade: idade2}

objetos.push(objeto1);

objetos.push(objeto2);

And like now I wanted to organize it in ascending order according to the value of age.

Detail: I’m using the localstorage to store the data, and I want to do everything in javascript.

You must pass a comparison function as parameter of sort:

objetos.sort(function(a, b) {
    return parseInt(a.idade) - parseInt(b.idade);
});
