This one is much more effective if you do it right:

Give a man a fish... And he'll take care for it for the rest of its life, or throw it back in the ocean where it belongs, or take it to an aquarium where they can take better care of it, because you can do other things with fish than eat it

Talking about fishing : I went to the Philippines some ten years ago, and visited several islands. One of them was really beautiful (blue water, white sand, etc...) and one guy lived near the beach, in a small wooden house. He would go every other morning fishing, and spend the rest of his day sleeping or enjoying the water. At first, I thought, wow, what a dull life. And then realized that I had worked two complete years to afford spending only five days on this very same paradise island - flying so far away from home will be for me a once-in-a-lifetime event ! - and honestly wondered : actually, whose life is the dullest ?

Teach a man to fish and he'll sit under a tree and drink beer all day!

You know you've posted this too many times when Chrome auto-completes the subject line for you!
Anyways, I have this function:
function initializePage(raceList, hlsList) ...
(for demographics, race and Hispanic/Latino/Spanish, of course, a "I don't want to answer" is accepted) but anyways,
Randomly, the list would not load. Really hard to reproduce locally, would happen once every 10 or 15 pages loads on the real site.
Those lists, and others, are acquired from an Ajax call that only calls this function after all the lists have been loaded from the server. Of course it's a stupid way of doing it, but at the time... Plus this particular page used to only have those two lists, but then it grew to more things...you know how that story goes.. and of course what's worse is that this is the only page where I seem to have forgotten to refactor the code and do it "the right way."
Anyways, in one place, I accidentally forgot to pass in the lists:
initializePage()
which resulted in the random "why isn't the list showing up" error.
I blamed my SPA code, I blamed jqWidgets, I blamed my mother.
And after staring at the code for hours over several weeks, I finally actually saw the offending line.
God, I want parameter type checking. I know, use TypeScript or something.

Rule #1 for every JS function I write: Check for undefined, null, and empty values if I don't want them.
I do null param checks as the first line of code in every .NET method, why would I do any different in another language? is my thinking.

Good point.

I agree, but in this case, I know the data was there, it was an error in the parameter list. And yes, Rule #1 would have caught it.

I use javaScript for what it does, expect from it no more than what it is. None the less, I feel sympathy for your never-ending distress on this topic. Perhaps?[^] will make all of the pain finally go away?
<script type='text/javascript'>
return;
</script>

You're looking at JavaScript the wrong way man. Really, this stuff is a result of not being used to JS. Welcome to the fun. You have to look at it like this, JS is a language that's finally growing up. But, it's powerful in its own right. You can do some pretty amazing stuff with it, provided you learn its quirks. One of which you obviously know about now. 
It's a flexible language. That's the idea. That's the idea of the web even, and so JS is no exception. However, you must also deal with this as a result. ES6 provides some new stuff, but you can achieve what you're after regardless...
Handling required parameters in ECMAScript 6[^]
Is it totally different than C#? Yes. But once you get used to the flexibility, it does more good than harm.

You're absolutely right.[^] I'll endeavor to break the pattern and write an "I love Javascript" post.

And I know it's been said before, but you really want to look at TypeScript or at least ES6/2015 transpilers. It will make your life easier and save some hair in the process.
