> Just like JavaScript, it won’t go away easily. No, not "just like." Whatever you think of JS the tweet above this quote doesn't apply-- I don't constantly have to look up how a function callback works, or how to do math. To be "just like" shell scripting, you'd have to get JS devs to start regularly using `eval` in lots of unnecessary places, plus using arbitrary, inconsistent use of single-letter aliases for some of the core methods I mean... > set -Eeuo pipefail Upper and lowercase! And the flag meanings aren't even explained in this article! Edit: To be honest, this reflects my own mental model for shell commands: commandName -garblegooklegarblegookle myArg1 myArg2 etc..

Hey, the flag meanings are explained in the article I linked in the post: > For details on what options exactly set -Eeuo pipefail changes and how they will protect you, I refer you to the article I have in my bookmarks for a few years now.

About "just like JavaScript" - it was sarcasm ;-) I write in TypeScript daily and still make fun of JS. But I agree, Bash is worse!
