I've seen many people facing performance problems on the @nodejs platform or even on vanilla JS on the browser and when I ask what's happening they usually blame the language. /2
Although, when I look at the implementation, I see they are trying to process all the data simultaneously. /3
They try downloading all the data in memory and the Node.js platform warns something like "you've been using too much memory, are you sure you're doing it right?"
What do they get with this info? 😬 /4

"Uh, #Nodejs or #JavaScript cannot handle this heavy task, let's jump to a better language such as #Python..."
If you've heard the same speech or are facing performance issues when processing large amounts of data in JavaScript then I have something to help you! /5

I made this video about one of the currently most powerful JavaScript features, the Generator Functions.
In summary, the Generator Functions let you process terabytes of data, if you will, by paginating data and processing it on-demand as the data is available. /6

In this video, I'll teach you how you can use it in practice 🔥 /7
I made a very useful example of a data integration process where you:
- consume data from a server
- request detailed info for each individual item from another server
- process it and submit it to a 3rd server /8

Using the Generator function would help you to unlock your apps and process even more data using less processing power
