Greate quote from Agile Software Craftmanship describing some of the short-cuts in programming languages. Classical example – function call versus arrow functions.

“…the ratio of time spent reading versus writing is well over 10 to 1. We are constantly reading old code as part of the effort to write new code.Because this ratio is so high, we want the reading of code to be easy even if it makes the writing harder.”

— Robert C. Martin

Why arrow functions are still not everywhere in the code.
