I'll throw in Brian Lonsdorf's "Professor Frisby's Mostly Adequate Guide to Functional Programming" https://drboolean.gitbooks.io/mostly-adequate-guide/content/ https://drboolean.gitbooks.io/mostly-adequate-guide/content/ And the related video series on Egghead (which I think requires a subscription) https://egghead.io/courses/professor-frisby-introduces-composable-functional-javascript https://egghead.io/courses/professor-frisby-introduces-compo... Which reminds me, if you can get an employer to pay for an Egghead subscription and/or a Frontend Masters subscription as part of a training budget, both are great. Also probably worth buying on your own if work won't cover it.
