The (!! - not not) trick is used in js to convert a value to Boolean and ensures a Boolean type. JavaScript has a weird mechanism of evaluating a value to either Truthy or Falsy


This link explains more on that

Hello guys.
Just for encouragement:
I only started learning programming around May this year, and I just made it into the fellowship.
So if you just started programming, you too can get in soon, but u have to give it your all.
Right from May till now, it has been non-stop, no-sleep learning.
Three weeks before the bootcamp project, I had zero knowledge of anything backend. Node/express/database, I didn't know any of them. At the start of the bootcamp project, I didn't know how to use git. How I was able to cover so much in very little time still surprises me.
Get good resources and keep studying hard!. Your hard work would pay off soon.
Special thanks to my ogas Don Pikko, guente02, isarray for assisting whenever I ask questions here.
The journey begins, there is still a lot to learn.

Thanks fizzle, pls is node.js different from express? I normally see them combined tho.

I used to ask same question too till I discovered expressjs makes backend development in JavaScript easy. It's built on top of nodejs. For example writing a simple server in express Js is simpler with less lines of code than in node. So basically, your work is made easier using high level expressjs to low level nodejs. So expressjs is a child of node which has other frameworks built on it. Hope this makes sense?

i understand below is a "class".

.block:nth-child(even) {
background: red;
}

when do i use nth-child....

i searched google but still got confused


The JavaScript code gives you 2 dimensional array i.e array in array like nested if statement. It's to generate pascal triangle. say you input 3

the result would be
1
11
121
it will always initialize the first and last number to 1 and add the number directly above it together.

You need to learn JavaScript. Then some backend like node/express js.
Bro the most important thing required for you to apply is; passion and the ability to learn.
Good luck. I also applied too

Hi.
Fourth week you'll be using the Fetch API (which is very simple) not Ajax (except things have changed). What were u asked to use in the instructions?
I saw some Fetch API links shared in the previous page.
This is a short and simple tutorial on Fetch:
https://flaviocopes.com/fetch-api/

By the way, you might not even start challenge 4 in bootcamp. On the last day of bootcamp, we were only expected to have completed challenge 3 of the project.
Our defence on the last day was on the project up to challenge 3.
I just started my challenge 4 yesterday.
Next week, what you'll be doing mostly is modifying your challenge 1 and 2 work based on the feedbacks you'll receive from your LFA.
However, that might not be the case for all bootcamps (this was my first bootcamp, I dont know how other bootcamps are).
So its always good to be prepared for everything.

Na as you talk am e dey go. I never touch challenge 3.
