.assert(condition, message = nil) ⇒ Object

perform simple assertion like c <assert.h> implementation raise an exception instead go to abort two ways how use assert: 1) assert(condition, “message”) 2) assert(condition) do “message” end I would prefer use 2.nd way because 1.st way always evaluate the message parameter (“like #failed_varfailed_var.some_info…”) while 2.nd evaluate message only if condition fails
