It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.

Itโ€™s time to get your learn on

Feel free to comment with what you learnt and/or reference your TIL post to give it some more exposure.


Summarize a concept that is new to you.

And remember, if something you learnt was a big win for you, then you know where to drop it as well.๐Ÿ‘‡๐Ÿ‘‡๐Ÿป๐Ÿ‘‡๐Ÿผ๐Ÿ‘‡๐Ÿฝ๐Ÿ‘‡๐Ÿพ๐Ÿ‘‡๐Ÿฟ

Editor guide

I designed Backend in Express and MongoDB

The backend is designed for a E-commerce store, and working on frontend, which will be designed on ReactJs;

Previously I made a full stack e-commerce store in MERN stack but with Redux and a bad css, but this time I am focused on creating a strong backend with validation etc etc...

๐Ÿ™†โ€โ™‚๏ธ, And hopefull will finish the react part next aur next next weakโ˜บ๏ธ..


That's awesome! ๐Ÿ”ฅ

Yes, that's awesome!


Awsome bro. If u nedd any help u can ask me


I learnt kind of-Object Oriented Programming in Rust. That was something. In fact I learnt a few more things about the Rust and its patterns while building an interpreter. Damn! That was tough.

September 30th, I am going to release ekscript.com. So working quite hard towards it!


I designed a workflow to deploy a react native application using github actions and write my first post in dev.to :D

And change App Center to github actions because the limitations to run e2e tests and manage the distribution of the binary have many problems for a product that plains publish 2 release by week.

Also I study a lot about metrics, logs and performance monitor to know the health of our application on production.

I hope finish my post about how to deploy a React Native application using github actions this weekend.


I've been building gRPC microservices in golang for my raspberry pis.
Learning and understanding what it MEANS that everything is a file in Linux has been awesome and I'm starting to appreciate it.

Golang is really great, channels are cool, and everyone should include arm32 as a target for everything!


I had my first tango with $emit in Vue this week!

I'd read about it in the docs and seen it mentioned around the twittersphere - but after having use it in a real-world application, I have a much better understanding of what, how, and why it's used.


it might sound silly but it was a huge win for me: I finally managed to start my first docker container and connected it to DBeaver and my Laravel project! :D after sooooooo many tries and conflicts and outdated guides hahahaha
all this pain in a single line:
docker run --name mysql-container -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password -e MYSQL_ROOT_HOST=% -d mysql/mysql-server:latest


-Basic use of Inkscape, I am learning it because I want to be specialized in image processing and computer vision and I want to play with open source graphic design programs, to implement newer versions using web technologies especially web assembly.
-Advance selectors on CSS
-Tricks to overwrite !important in CSS


Recently, I decided to devote my attention to multiple things at the same time. So, I started off with learning Nodejs and little bit of express. In the midway, worked with a startup on their upcoming android app and lastly ended with a freelancing job as a ui developer. I'd say a pretty productive week.


Hashmaps are slower than one would think.

I tried to make the map/dictionary in my interpreter faster

So far it was either an unsorted array or linked list of key/value pairs. Basically the worst way to implement a dictionary.

Now I have changed it to using hashmaps. But with the hashmap it is 30 % slower in practice.


I did a deep dive into workings of tr and sed commands for my submission related to the GitHub Actions Hackathon! It's a fun one ๐Ÿ˜œ


I learned about the Elevation helpers in Angular Material. I'll be using them in my revamped portfolio (sneak peek).


After 3 AWS certifications, started preparing for the 4th one: AWS SysOps Administrator.
Taking the exam on the 7th of September!


My first React frontend project is done. I'm gonna connect it to my first GraphQL back end project, which I'll start working on today ISA


I created and merged my first ever PRs on github!


Building this: hidden-taiga-78457.herokuapp.com/
and: tanvesh.vercel.app

And learning some native android development from udemy.


I learn how to present a 10 minutes talk on Nomad PHP.

It's about the Green Button, PHP and JavaScript :). Check following tweet:



Thanks for asking! Batch Normalization techniques for optimizing neural networks made on Keras/TF, in Python.
