> What are some need to know things in terms of frameworks and workflow that I should be aware of?

Strange times, isn't it? 10 years ago, a front end job would require a comprehensive understanding of CSS, the DOM and JS. Now it's all about framework X and Z, build tool A or B, Typescript and what not, like these tools are so complex one has to be a specialist in these tools because they can't be learn in a few days.

Meanwhile, micro-services are all at rage on the server and back-end developers deemed big frameworks like Rails,Spring,Symfony and co an anti-pattern because complexity is bad (Go)? But stupidly complex tools and frameworks on the client are OK?
