Start with the basics. Angular is not basics. Angular is a JavaScript framework for coders that know JavaScript, HTML, and CSS.
I am not trying to discourage you. A passion and self belief in this career is a must. But you must also be realistic. You not ready for Angular yet. Learn JavaScript first: especially classes and ES6 modules if you want to use Angular.
