I'd say JavaScript makes my work as a content creator so easy sometimes 😂
There are so many new proposals and new features coming to the language that we could discuss a whole week about it haha.

Today, I brought something interesting that I was missing for a while: Immutability in arrays!

"Yo, why are #JavaScript and its ecosystem so messy?!" 😡
Well, I am glad you asked... Let me tell you a story! 🤓

For starting... #JavaScript was not designed to be the language that it is today!
JS was created in 1995 by @BrendanEich for Netscape, a web browser that was trying to come up with a language to make the web more interactive

@BrendanEich #JS wasn't related w/ #Java, so why did they call it Java-Script?! Duh! 😳
Java was trendy! it was possible to build interactive sites by embedding Java apps in pages (applets). So it was mostly a #mktg move: "JS: the lightweight Java alternative" or something like that I guess

wooowwwww, I know that you've always wanted to compare objects in JS as `obj === obj` so I brought good news for you 🤩🔥

I don't know about you but I'm really excited about this feature, let me show you how it works 🔥

The #ECMAScript proposal for the #Record and #Tuple value types is Stage 2 which means that it could change at any time but there're packages and playgrounds for you to try out this feature before it's available on the language.

Como resolvi um bug no @nodejs que afeta o @Facebook Jest, @yarnpkg e milhares de outros pacotes 🔥🤩

Para quem não sabe, há um tempo atrás consegui resolver um bug no Node.js que impedia que sub processos se comunicassem com o processo principal quando usássemos #ECMAScript modules /2
Fiz até um vídeo no canal mostrando todo o passo a passo, vou deixar o link no final do post para você assistir depois!
Minha primeira contribuição foi realizada na versão 17 do Node.js, só que até então, o problema não havia sido corrigido na versão corrente /3

Un feature #Javascript en stage 2 (que llegará pronto a una futura versión de #ECMAScript!
Finalmente vamos a tener estructuras de datos inmutables!: tuples y records ❤️
Un record es un objeto inmutable, y empiezan con "#"
Al tener inmutabilidad, podemos comparar 2 records!

Y una tuple es un array inmutable. Se declaran igual que un array, empezando con un "#".
También podemos comparar dos tuples sin pasos extras.
También podemos comparar dos tuples sin pasos extras.
En Javascript no podiamos comparar 2 listas o 2 objetos de forma sencilla, porque al hacerlo se comparaba la referencia, no los valores.
Algunas esct. de datos inmutables tienen algoritmos para generar un id dependiendo su valor. Al comparar 2 estructuras, se comparan los ids.
