Bash is the programming language where an empty if block is a syntax error
-
Bash has arrays. Trying to use an empty array is an error.
Bash has pure functions, and by "pure" I mean they cannot return anything so they report results purely and exclusively through side-effects

-
PHP, JavaScript: "lol triple equals sign" Bash: [earliest versions literally had no syntax for comparing variables]
-
And let's not forget Bash's jaw-dropping default behaviour of "If something goes wrong, just keep going"

@qntm@profanegeometry they can return numbers from 0 to 255, can't they? -
@duckinator@qntm sort of, but anything other than 0 implicitly means "hey this thing didn't work right" to a lot of things - 1 more reply

@qntm I was like “I must be missing some documentation. How do I return something from a function?!?” -
@jasonmp85@qntm you print it. A function from a library in any other language isn't supposed to, but in bash, that can be your return value
