My honest advice would be pick a tech stack, for which going through the code or understanding the syntaxes is easier for you, don't just pursue technologies that are hyped up, start small, understand the problem solving, basic design patterns and once you get hold of a technology stack then start applying to the companies. Remember one thing if you'd limit yourself to a framework development you are limiting your growth right there.
