Summary
Core Theme
The content humorously critiques the complexity, instability, and constant evolution of the JavaScript ecosystem, highlighting the perpetual need for developers to adapt and rewrite code despite its ubiquity.

well that was our tool chain from last
let me just put this
i have a three production already just
four my job is to keep our code running
while other packages are changing theirs
should you learn javascript nope is
there any other option no oh look
another library was added today to patch
the problems of the other 150 that were
also released did you know javascript
was actually written in seven days such
a messy language i love it did you know
javascript was actually not written in
seven days no one ever knows what value
variable is or what its type is now we
use typescript we still don't know i'd
rather use rust or webassembly they say
adoption is coming
they said that 10 years ago they say
that every year but this year is
different is it scalable no is it
maintainable no is it portable
not really yeah we use react we actually
use pre-act we actually use svelter we
actually went back to vanilla javascript
yeah we're using a library for this that
we rewrote to vanilla javascript because
it wasn't efficient we're stuck with
this messy language now
i love it javascript yeah it's the de
facto standard do you know there's a
library for that i wouldn't trust the
let's say finance application with
javascript what our finance application
does is totally fine to use javascript
but i'd recommend using typescript not
that we do we had callback hell
and then we went to promises await came
out went back to promises and now we
rewrote everything back to callbacks
because it's just more comfortable
at least you know it's bad oh it's
probably just a quick fix will take me
three to five days to find it we tried
coffeescript rewrote our codebase try
typescript rewrote our codebase and then
we went back to vanilla javascript
because it's just more comfortable so we
rewrote our codebase again yeah we used
react and then react 16.8 came out and
we had to rewrite everything to hooks
react 17 came out we had to rewrite
everything again and then react script
was updated to version 0.4 and we had to
fix everything
to work with local images and now react
version 18 is coming out we'll rewrite
everything again we rewrote our code
base around nine times this month yeah
you can use redux totally fine but but
if you're on it i'd recommend you use
redux toolkit but actually it's better
to use flux or flumax or flexible
actually better to use recall not that
we do but now react came out with the
hooks and context api which apparently
is better than redux apparently we'll
rewrite everything again sometimes it
just doesn't transpire we usually
rewrite our code base now we actually
wrote a custom transpirer to transpile
transpider it's such a messy language we
use it for our website desktop app
mobile app for the fridge the tesla is
not actually native i mean it is
actually native but it's sort of not
really native it's sort of hybrid native
but some of it is native i mean some
people use it in a native way
but we don't really use it in a native
way technically a lot of people are
switching back to native no one has
switched yet angular
talk to me when you use angular 2 or
react npm is such a bad package manager
no one uses that anymore npm is such a
good package manager how many languages
have one so that major version breaks
our code but our code breaks the minor
version i still don't know how to fix
pure dependencies until this day
yarn bpnpn turbo would make sense right
javascript doesn't think so jquery what
are you five
we use jj query global variables
no one uses them it must be somewhere in
the window how do you debug node apps
you don't you just write good code but
not in javascript no one ever masters
javascript i get a hundred thousand
points in stack overflow i'm still a
noob node is technically multi-threaded
javascript is technically performant our code
code
is never safe when they'll blow up
probably won't work anymore probably
will be using rust or webassembly or
whatever j s an array is technically
just an object object or object null is
technically not an object but objects
can be known so they technically can be
non-object unless they're an object
right so technically null is an object yes
yes
it's a bit hacky i admit
but javascript is by design is it easy
have you tried javascript probably will
be a bit hacky have you used javascript
before i don't recommend i don't like
our tool chain documentation
and another advantage is that it's free
so was java before it was bought by oracle
oracle
so we prepare ourselves by installing
modules from npm then we compile it to
typescript then we use a term spyler
called bubble to transpile it to es5
load it with system.js file for
bankruptcy bundle it all up with webpack
use it in a framework like react and let
the state be managed by redux or flux
flummox or flexible or recoil or
whatever js and voila
all of this just to avoid using jquery
or in our case jj query but that'll be
probably less performant
as most of the things this isn't our
production code it will be tomorrow
though probably gonna get fired again
i mean there's really no alternative to
javascript right now de facto no one
really knows what the value is until we
get an error
i love it well try writing anything
without javascript nowadays javascript i
love it
