How can I stop processing until setTimeout() is done?

Assume this please:

setTimeout(function(){
    console.log('one');
}, 3000);

console.log('two');

I want to print one first, and then two in the console. current code prints two first.

How can I stop processing until setTimeout() done?

Noted that, I want to execute setTimeout() once. not each 3 sec.

Here is my real code:

var arr = ['mohammad', 'ali', 'zahra', 'fatemeh'],
  res = [],
  status = true;

function myfunc() {
  if (status == true) {
    alert('test');
    console.log('Engine started fetching a new one!');
    status = false;
    $('.im_dialogs_search_field').val(arr[0]);
    $('.im_dialogs_search_field').trigger('change');
    setTimeout(function() {
      if ($('li.im_dialog_wrap').length) {
        res.push($(this.find('.im_dialog_photo').attr('src')));
      } else {
        console.log('There is no result for ' + arr[0]);
        status = true;
      }
    }, 3000);
    arr.shift();
  } else {
    console.log('Engine is bussy!');
  }
}

When I call myfunc() function, it always throws Engine is bussy!. What's wrong?

setTimeout(function(){
    console.log('one');
    afterTimeout();
}, 3000);

function afterTimeout(){
    console.log('two');
}

hope this helps.

move console.log('two') inside timeout Try this

setTimeout(function(){
    console.log('one');
    console.log('two');
}, 3000);
