Today's class was on the next level.First, we wrapped up writing controllers using express & prisma.Then,the actual fun started & we learned asymmetricEncryption, openID-connect & SAML standards, accessRefresh tokens. @Hiteshdotcom @piyushgarg_dev @yntpdotme @nirudhuuu

This is how we did authentication in our cohort.

we wrote more controllers in JavaScript for our authentication system using Express & MongoDB. Then we switched to the PostgreSQL database using Prisma & Neon. Also, we learned the art of debugging.

Today, we continued our authentication system in the Cohort. Wrote controllers for Register, Verify user & Login.
Learned about JWT tokens, many packages like nodemailer, bcryptjs etc.

Therefore, be cautious while operating on the database.
You can use try,catch,async,await.

In the recent classes of Chaicode Cohort, we are almost done with JS fundamentals:
- Proxy
- Promises
- Promisification
- Async await
- Global execution context
- Lexical scoping
- Closures
with @Hiteshdotcom sir & @piyushgarg_dev sir

[Shivank Bhardwaj @Shivank44444]

Ep14 of Chaicode Cohort: Deep dive into JS internals.
HLD & LLD of JS components:
Call stack
Microtask Queue
Callback Queue
Event Loop
Global execution content
Note: Hoisting also happens in let & const, but the temporal dead zone restrict access.

In the 13th class of Chaicode Cohort, we went through the basics of js & solved some challenges.
What I learned:
-the objective isn't only to execute the code, but rather to analyze how and where it might become stuck or encounter issues

Done with the 12th class of Chaicode cohort where we made a Todo app, manipulate the HTML code which we basically call DOM Manipulation. From today onwards we will be focusing on building a lot of things with @Hiteshdotcom sir & @piyushgarg_dev sir.
