Important Topics to learn/master to become a DECENT JavaScript Developer

A Thread🧵

I have seen most beginner web developers skip these topics and directly move on to frameworks/libraries.

The following topics will help you in your career, and they will also make you a better JavaScript developer.
👇

1.⚡️ Closure
A closure gives you access to an outer function’s scope from an inner function. In JavaScript, closures are created every time a function is created, at function creation time.

2.⚡️ Asynchronous JavaScript
We all know JavaScript is Asynchronous but mostly we ignore how it's single threaded execution is actually working.
looking under the hood of JavaScript's working will definitely help you to understand the language better.

3.⚡️ Promises
A Promise is a proxy for a value not necessarily known when the promise is created. It allows you to associate handlers with an asynchronous action's eventual success value or failure reason.

Someone tried to seriously demotivate me today (Thread)🧵💔

Today, I went to someone's house with my mother.
Let's call this person mr. A-whole.

(Just so you know mr. A-whole and I met for the first time.
We know nothing about each other. )

After 5 minutes of conversation..

with my mother he asked me, "What do you do?"

Me: "I am a final year CSE undergrad."

Mr. A-whole: "So, does your university have On-Campus placements?"

Me: "Yes"

mr. A-whole: "That is good. You should definitely try to get a job though placements"

🧵

Me: "Well, I have a different plan. I am going to further continue my studies."

(Obviously the plan is quite elaborate and I wouldn't tell a person who have met me just 5 minutes ago)

mr A-whole: "So M. tech.?"

Me: "No I'll do self study for a while. Not a degree."

🧵

mr A-whole:

"You don't look like a person who is disciplined. Through my experience I can tell you can't do self study. You should definitely try to get a job...blah blah blah my collogues destroyed their career... blah blah blah.

🧵

And then he spent the next 5 minutes ripping my dreams into pieces.
Shredding away my capability without having the slightest idea of who I am, what I do, what I am going through right now (which is a lot).

He basically told me I can't do anything (from looking at me once.)

How should one approach System Design questions during an interview?

Here's the step by step guide:

🧵👇🏻

System design interviews are generally open ended discussions. There's no one right answer.

The main focus in this round is to see your thought process and whether you'll be able to design a minimal system keeping future scale in mind and by following the standard principles.

Know that many interviewers deliberately make it hard to see how you approach a given problem.

You cannot possibly design a complex system in 1-2 hours which engineers usually take months to years to design, develop and build.

So this is how you should approach this round:

1. Clarify the requirements: As mentioned earlier the questions are generally very open ended. So you need to ask a lot of question to set the scope clear for the discussion.

Example: "Design an application like Twitter"

Twitter has a lot of features like:
- Post tweet
- Home timeline
- Profile timeline
- Analytics
- Likes
- Retweets
- Following
- Bookmark
- Trending etc

You get the idea!

Found your neighbor on Parler map and want to see what video they posted, here's how.

Here is an easy to follow step by step guide on how to locate your neighbors who used Parler and then view and Download the videos they posted. A thread.

1. in the beginning, browsers didn't have download statusbars
2. firefox got a browser statusbar extension. it was configurable and worked well
3. chrome cloned it without options and it didn't work as well

4. firefox realized chrome was faster and more secure at everything and therefore dropped extensions
5. now firefox doesn't have a download statusbar either

6. someone reimplements download statusbars in firefox's new web-extensions format. it's terrible because of the inherent limitations of the significantly less flexible and powerful extension format

7. CHROME WINS! (with its terrible download statusbar implementation which can't be fixed by users, because No Options and No Skins and No Extensions)

this is where we are now
