as always you are incredible

Thank you, sir !! Im a freshman from philippines self studying js and this really helped me a lot ❤

wow bonus exercise was awesome to figure out. taught me how anonymous functions work here, still wrapping my head around it even though i know how it works, it just blows my mind! also didn't know map had a second argument class FancyArray extends Array { mapWithLogging(callback) { const newArray = new FancyArray(); for (let i = 0; i < this.length; i++) { newArray.push(callback(this[i], i, this)); console.log(`Current: ${this[i]} After Callback: ${newArray[i]}`); } return newArray; } } const arr = new FancyArray(); console.log(arr); arr.push(1); arr.push(2); arr.push(3); // console.log(arr); const mapped = arr.mapWithLogging((item, i) => { return item + i; }); console.log(mapped);

loved exercise 3, it was made SOOOOO well to really understand what's happening behind the veil you have so much passion in both programming and teaching which shows so much in your exercises and explanations. ugh can't get enough

100% extremely clear, love this

god i love this series. you're such an amazing teacher, this is so exciting

wasn't hard, but i was stuck on ex 3 for a bit because my dumbass forgot to await LOL it's always "how do you test your code" but they never ask how my code tests me smh

Hey Nadar your promises was amazing, can you reply to this comment the extensions you are using for the cursive text in your code and the animation in your typing cursor

i didn't even really think this was something you had to wrap your mind around, unless I'm being naive, but I always assumed it worked this way haha

i think the hardest thing about recursion is the mentality you have to adopt. Took me 2 days and fully gave up on bonus exercise. It makes sense in retrospect, but it takes me a really long time to think in recursion. ex1. const palindrome = (string) => { if (string.length === 0) return false; if (string.length === 1) return true; if (string[0] === string[1]) return true; if (string[0] !== string[string.length - 1]) return false; if (string[0] === string[string.length - 1]) { let arr = string.split(""); // convert string to array arr.pop(); arr.shift(); string = arr.join(""); return palindrome(string); } }; ex2. this one was no joke, i just assume we couldn't use any loops until I saw how you solved it lol... const flatten = (array) => { if (array.length === 0) { return array; } if (Array.isArray(array[0])) { array.splice(0, 1, ...array[0]); return flatten(array); } return [array[0], ...flatten(array.slice(1))]; }; ex3. const flatten = (object) => { let flattened = {}; for (const [key, value] of Object.entries(object)) { if (typeof value === "object") { flattened = { ...object[key] }; delete object[key]; return flatten((flattened = { ...object, ...flattened })); } } return object; }; I fully gave up on bonus exercise. It was easy in retrospect, but it's really hard for me to adopt the thought process.

Omg, you talk soooo much😊, just go ahead and show the content for god sake

Hey nader ,I found your explanation vey clear, could u please explain useMemo,callback ?

Thanks for the explanation.

in exercise 3 i found that the best was to search first and then ask questions :D, well I was right, foundout that you can specify the number of occurrences with {}'s, my solution was const phonePattern = /^[\d]{3}-[\d]{3}-[\d]{4}$/

thanks nader

took me a bit to understand it and i think this is a really good way to look at the recursion array and even the binary tree 1 + (1+(2+(3+(4+(5+(6))))

thank you nader

WHEWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW I DID ITTTTTT holy moly, was this so satisfying to complete man, omg. it was interesting to see how we both went through it, i first started with the fetching because i was comfortable doing it as we've done it already, then i went with inquirer and i actually ended up watching a little on how to use path. but everything else i figured it out. god that was fun.

Great video to help us get first hand experience on programming interview. Thank you for uploading such great content 😊

i would like to comment to all of your videos, you are amazing, you explain everything sooooo well !! Proud of you really !!!!!

This is amazing! thank you! I do not have computer science background but this is super clear and easy to understand. I like that you breakdown each concept to the smallest bit and explain their connections. This helps so much!!!

best video best playlist good work brother😍😍😍😍

ex1 --- - var loggedIn = false; let i = 0; while(loggedIn==false){ console.log("incorrect login credentials"); i++; if(i==3){ loggedIn= true console.log("successfully logged in") }

ex 3 stumped me longer than expected, but i got through it looking around. the hardest thing was not really knowing what i was looking for, but as i got some inklings and matching names, got it together. also you simulating the struggle is so nice to assure that its expected to be like this sometimes

The way you explain and practically show with exercises, your playlist should be at the top of the search list. Thank you so much for taking the time to teach us, sir.

one thing about exrc3 Boolean(cool) its always gonna give value of true even if cool = "false" to solve that problem use JSON.parse(cool)

im happy if these are considered challenging because im still solving them without help. i'd say keep them this level!

thank you!

was stuck a little on the third one. I found that I was already comfortable not using "let" to initialize my for loops. Instead of splice, I actuallty was using filter and then updating the original array with the shallow copy. while it was working, i found using splice better after i completed the exercise. sometimes it feels like i have so many different options that i just go with what i think of immediately or at least works to get the result i want.

best explaination on the youtube👍👍

My brother Nader you are awesome 🥰🥰🥰😘😘😘

they are both very very weak

it seems simple, yet open ended in complexity. very interesting and eager to do the exercises

doesn't seem too hard, but curious why I would want to use this over if/else. 47/81. excited as i am nervous for the next project haha

I saw this is nodejs stream docs

haha he's making a simple question complicated. 🤣

My favorite teacher so far!

Awesome! Thanks Nader

Just want to add my solution to exercise 3 to the ecosystem for future devs. But not before I again thank you for this series, it has infinitely made my fundamentals better and decreased coding anxiety. What a time to be alive. let number = 1337; // random integer from 0 max as a reusable function const myRandomInt = (max) => { return Math.floor(Math.random() * max + 1); }; /* remember that even if you can't access what is in the try block, if the local scope alters something that already exists globally or share the same parent scope, you can still access it from catch block */ try { console.log("Number initialized at: ", number); //gets random new number, adds and redefines 'number' variable number += myRandomInt(1000); console.log("Number updated to random number: ", number); if (number < 2000) { // exits try block after failing throw new Error("You lose!"); } else { console.log("You win!"); } } catch (error) { console.error(error); console.error("Oof.... Number was too low: ", number); }

thanks

i watch this video 10 times untill i uderstand "undefined+!" is not function 😅

Thanks Nader, excellent video!

Wow, ngl this was kind of tough. part of it was trying to find the best approach, switching approaches, but I eventually did it on my own. Fantastic fundamentals flexor

thanks

youtube does not deserve this man, providing premium quality course

Keep going

Man you are really the best keep it up please

You prepare the best lessons I have ever seen. Will there be next js lessons?

thanks, Will there be a next js course???

You are very amazing, hoping great success for you ❤🎉
