Be careful though not to add too much on your plate, for you don't need to know 'everything'.
It is far better to be specific on the few stuff you actually really need for a particular job/project and focusing on those than to scratch the surface of many techs/frameworks/libraries without having mastery of any.
Dan Abramov explain that better in this recent post: "Things I Don’t Know as of 2018"
I agree. I was trying to get things that related to working with React and API's mostly. There should probably be an explicit ranking system of importance. I'll be ignorant of more things than I'll have a mastery. I've accepted that. 😁
