Do so:

console.time('teste');
for (var i = 0; i < 10000; i++) {
    // seu código aqui
}
console.timeEnd('teste');

In this case, your code will run 10000 times and at the end you know how much time has passed. Very useful for comparing codes to know which is the most efficient, e. g:

console.time('teste1');
for (var i = 0; i < 10000; i++) {
    $('#painel .lista');
}
console.timeEnd('teste1');


console.time('teste2');
for (var i = 0; i < 10000; i++) {
    $('#painel').find('.lista');
}
console.timeEnd('teste2');

In this example above, you find out which stretch is the most efficient: $('#painel .lista') or $('#painel').find('.lista'), using jQuery.
