> nowadays every 16-year-old web-dev reaches for Array.map(x => <div>{x}</div>) when they write their pages in the most popular framework. These higher-order functions have now become part of the “hello world”
It's just wrong to ascribe the popularisation of HOFs like `map` to Haskell. `map` was there in good old (practical) Lisp 1.5 back in the 1960s. Why ascribe this to Haskell (released 1990) rather than Lisp? Guido said Python v1 (1994) got HOFs "courtesy of (I believe) a Lisp hacker who missed them"[1], Ruby had blocks in V1 (1995). Haskell's research direction was not about very, very old news like HOFs, it was about non-strict evaluation, and cool type system stuff.
