Learn JavaScript Generators in Practice || Processing Data On-demand with Example || Erick Wendel

Hello, my friend. I'm Erick Wendel and welcome to one of the most important videos on this channel.

JavaScript generators, made to help you process large amounts of data, gigabytes, terabytes? you choose.

Today you'll learn in practice where a Generator function is better than a common JavaScript function and much more.

Well, open your favorite JavaScript code editor, get a drink and let's begin!

[zendphpcolombia]

finally a relative better explanation about generators, thanks

[henrique-marti]

Só nos "The book is on the table". Cara, que legal, sabe que esses vídeos ajudam a gente a aprender inglês tbm, né?

Além de ensinar JS agora está ajudando em inglês tbm, show demais.

Dúvida técnica agora: como ficaria o "CRUD é o cacete" em inglês?

[TheSostenesg]

Mano. Muito brabo, Erick. Massa que tu vai falando devagar, aí já consigo entender o que estás dizendo msm sem legenda. Isso ajudar muito no aprendizado do inglês e de JS. Mais um conteúdo top, seniorzao.

Dear Erick, Could you publish more a video lecture on learning " Transactions and Concurrency Control With Node js for Mongodb and Mysql", I really love you so much!

[soniablanche]

You can convert a readstream into a json by using the json function in the node:stream/consumers module, but it's still experimental as of Node 19.4.0.

Bom dia Erick, show demais esse video. Dessa maneira, qual seria a forma mais interessante para informar qual a porcentagem de dados que foram processados? Vendo de uma perspectiva de onde eu quero mostrar pro meu usuario final a velocidade do que esta acontecendo sem pesar a aplicacao salvando logs no banco por exemplo.

[edmonstro]

Muito bom! "Brazilian" invadindo o mundo. Parabéns pela "ousadia" e conteúdo!

[brenopereira]

Man, thanks for this video. Right now I have a challenge on a project that is paginate a list with 150k costumers and I don’t found it a solution but now I have :)

[moylababa]

may I know, when will you release your nodejs stream course?

[mykun]

Hi Erick When is your node js stream course released?

[VictorHugo-victorvhpg]

Parece aqueles indianos falando em inglês
