So Cassie Evans tweeted this the other day:
Frameworks obfuscate away & front-end dev spans so many specialities.
When there's a 'discussion' on here it's common to see folks say 'learn the web platform'.
Got me thinking.
What's the most useful thing you've learnt about the web platform for YOUR area of expertise?

This got me thinking about a thing that it literally took me YEARS to understand (and frankly severely hampered my coding skills during that period.) And when I say years, I don't mean like 1 or 2 years. I started learning BASIC and HTML/CSS around 2000, and have been on and off developing since then. So by years, i mean about 15+ years.
The thing about functions...
So the thing I never learned is that a function isn't some magic thing. Most languages allow you to pass functions around. As arguments. To other functions. This may seem obvious to others, but seriously, I did not understand this concept. Because I didn't understand this, GUI programming was impossible. JavaScript event handling was not understandable. Certain parts of WordPress were incomprehensible.
I remember trying to learn to use PyGTK, and never being able to do much with it.
One day though, I think I was reading some JavaScript code at my first professional programming job, and I suddenly realized you could pass a function as an argument. SO MANY THINGS CLICKED FOR ME. All at once, the ability to use a bunch of libraries that I could not understand before became open to me and it completely revolutionized how i think about things.
So, for all you new to development, understand this: You can pass a function as an argument to another function.
Thank you.
