I found some good tips to write robust and maintainable software. After reading the post, here is the extraction of this article-
Rule 1 — Don't use goto, rationalize the use of continuing and break, don't use the switch.
Rule 2 — Prove that your problem can never create runaway code.
Rule 3 — To do so, limit the size of it. Usually using pagination, map/reduce, chunking, etc.
Rule 4 — Make code that fits in your head. If it fits in a page, it fits in your head.
Rule 5 — Check that things are right. Fail when wrong. Monitor failures. See rule 7.
Rule 6 — Don't use global-ish variables. Store data in the smallest possible scope.
Rule 7 — Let exceptions bubble up until you properly recover and/or report them.
Rule 8 — If you use transpilers, make sure that they solve more problems than they bring
Rule 9.1 — Don't use references even if your language supports it
Rule 9.2 — Copy arguments instead of mutating them, unless it's the explicit purpose of the function
Rule 9.3 — Use as many type-safety features as you can
Rule 10 — Use several linters and tools to analyze your code. No warning shall be ignored.
