Gender variability as declarations in JavaScript: const / let / varMeme is based on Jordan Peterson "approival / disapproval" format, him being a conservative who disapproves of gender fluidity.

Can anyone explain it to me, please? ๐ฅน
In JavaScript, a const variable is an immutable constant that you cannot reassign. Similar to how many conservatives think of gender, an intrinsic fact of a person that you can only read, but never change.
The "let" keyword declares a variable in a local scope, the nearest surrounding curly braces. It can be changed in that scope, but does not exist anywhere else. I assume this is meant to concede that gender is a spectrum and your presentation can kind of wiggle, such as between "very manly" and "not as manly" but still a man. Like, a stereotypical lumberjack and a stereotypical twink are both men so there isn't "one way to be a man" but a conservative might say " but they are still men, you can change how you present but you can't change sex".
The "var" keyword lifts the variable definition to the top of the function, or "hoists" it up. A variable declared with var can be accessed and modified anywhere after the block it was declared in. Gender is a spectrum and it can be reassigned anywhere, at anytime, to anything.
I interpret it a bit differently. After all, a variable declared with var isn't really more capable of being rebound, or bound to more values, than one declared with let. However, it is possible, with var, that setting a variable in one place could change it unexpectedly in another, so Rose Noble coming out as trans could cause Jordan Peterson to also suddenly be a woman.

similar to how most liberals think of gender
I thought this was obvious.
Douchebag Peterson doesn't deserve to be a meme.
python:
gender: Optional[str] = None
How about:
gender: Optional[complex]
self.gender = 1.63-2.1j ๐ค
Anyway you put it it's not gonna please non-binary people.
NB here - this is hilarious.
Joke's on you because they're all still mutable objects behind the reference.
Last one can be freely changed by anyone, the middle one still has some restraints.
var isn't global unless it's not inside a function. var is just function scoped, with declaration auto hoisted to the beginning of the function. let is a little more intuitive since you can't refer to it before it's been declared and has block scope rather than function scope.
Reassignment isn't the same as mutation. But mutation depends on the type of value. If gender was a string like "female" it wouldn't be mutable cuz strings are immutable in JS.
