Joining a new company, here I have to get command on Java Spring boot and Angular. Till now I have mostly worked in Python/Django/GraphQL so don't know much TS or Java 🥲

+ I am a very slow reader so documentation will take a lot of time for me.

If you know any good (latest updated) resource, that would be of great help :D

Best Spring boot and Angular Tutorial?
