Saudades do conteúdo em português. Óbvio que é uma obrigação um dev saber inglês, mas não é algo que a gente aprenda de um dia para o outro. Por favor, não pare de produzir conteúdo em pt também, a galerinha que ainda n sabe bem inglês agradece.
Como sempre, seu conteúdo é TOOOP

Dear Erick, Could you please make a video lecture on " Multithreading programming for queries mongo db and mysql with node js worker_thread"

[santiagoaguilar]

It's all great function but I get in love with the group function, it's amazing how you do a lot in such a short code.

thanks! Could you please publish a video on buiding your own a proxy server provider from scratch with node js? I want to build myself a proxy server to use for comfortable anonymous browsing in the browser.

consumo conteúdo em inglês porém eu tenho um carinho especial para os produtores de conteúdo br, pelo fato q é dificil acha muitos assuntos em pt-br, eu sou uma batata porém seria interessante ter a opção do video em pt-br.

Hello! Good video! New features - it`s good! But is anywhere in new ES standards any feature about private members of a Class? I`m using in my practice WeakMaps to implement a 'private' member - but it`s a bit difficult😀.

A little trick is that you use a mac computer from apple that will produce better quality recorded video than a windows computer, but anyway your video is very sharp and awesome, font size and width length size are very reasonable to watch, i enjoy from your video, thanks!

O dev brasileiro já tem uma carência muito grande de conteúdo em pt-BR e ainda vem BR meter conteúdo em inglês... é de cair o cu da bunda mesmo
