Что можно сделать в такой ситуации?
Что от них хотят?На доучивание у меня примерно месяц (два от силы), правда с почти полным погружением. Возможно ли за это время дотянуться до Junior JavaScript Developer?
На что делать упор в занятиях: пилить свой проект или проходить курсы? углубляться в "голый" JavaScript или разбираться с frameworks (какую выбрать?) и базами данных? Или вообще хватит умения обращаться с AJAX?
