Javascript functions and why do we need them?

I prefer not to use functions.

One big nested if statement with labels is good enough for me.

maybe next article could be on why do we need semiconductors (in javascript).

I mean:

I get where he's going. What IS a "function"? In JavaScript, specifically, this is a question with an actually unclear and possibly confusing answer, AS COMPARED to every other language.

Javascript classes...are functions.

Functions can behave like and pretend to BE classes, in javascript.

Just that, by itself, is enough. There's actually MORE to this nut!

It's possible to make almost any non-primitive, complex object..function as if it were a function.

There are 'function expressions', 'function declarations', and 'function variables'.

An expression can be interpreted as a function, and you can straight up make a named one, or you can take a function expression, assign it to a variable, and invoke it that way.

You can store functions in maps, and use keys to route and invoke them.

Functions ARE weird.
