- In this video, I walkthrough a coding challenge I had during an interview. This is the palindrome coding challenge! I demonstrate how I accomplished this with React JS.
Venmo Me a cup of coffee:

Good stuff kev!! I wish you keep rolling new content, even for more advanced devs!! I'd really appreciate that!
Thank you! I will keep more content coming for sure. Working on more things like career advancement advice or other intangibles that we don't get taught about in school. Stay tuned and thanks for subscribing! đ
Love it!!! keep it up!!!
Thank you so much! Really appreciate you saying that. đ
you're a cool dude man, keep it up I like the way you tackle the error/bugs haha
I really appreciate that, thank you so much! đ
Thanks Man.. You are good đ
Thank you! I appreciate you watching đ
Kevin has the best videos !!
Thank you so much đđ I hope you're doing well and moving on to something good
Nice one kev , thanks (:
Thank you so much! More to come, been taking some personal time, but I have a couple videos in the queue for editing to give to you all. Stay tuned :)
Hey Kev love your coding challenges , I have a small request if you can please zoom in the code while you write it would be
much more readable for viewers.. Thanks again
Thanks so much, and thanks for the feedback, I'll keep working at things to make sure my code is visible :)
Do you ever come across algorithm and data structure kind of technical interview? Do you only apply positions that is frontend or do you go for Software Engineer position as well?
Great question! Personally, I don't apply to positions that are data focused. I like the creativity of working with web facing applications. Software engineer is a very broad term these days, no longer reserved to the traditional "software". In my current position I do full stack development as well as leadership responsibilities. What kind of video would you like to see around data or software engineering?
Hey Mate, appreciate the videos. I have an interview tomorrow and your videos are super helpful. Just a point at around 24-26 minutes you said we need to clear the array, you mean(?) after joining palendrome, we have string instead of the array that's why we don't have push function for string and in the clear function, you assigned empty array again in clearPalendrome.
I hope I understand correctly.
Hey I hope your interview went well. Yes, we want to clear the array after joining the palindrome. The variable we assigned with an array will still contain a value because we join the array in a different variable assignment. So we need to explicitly clear the array so it is ready to take in a new value. I hope that helps :)
Damn this is mid level? I'm self taught in React and would love a job in dev but can never get interviews, not sure what to do. I've built a palindrome checker, re-built Disney+ website along with Firebase auth to log in and register, no payments for subscription implemented though or video plays of course. I gave up and stopped coding for the past 7 or 8 months as I was pretty burnt out and getting nowhere but I can feel the fire re-lighting - any tips?
Hey Joe, wow good job on all your projects! I've been where you are. Keep your head up and watch my "how to interview for a developer position" video. I haven't put in an application for at least 3 years using all those tips đ€
Hey kevin nice video bro . But i got eye problems and I am unable to see small text , can you please zoom in next time . Subbed your chanel , keep going
Thanks bro, yes trying to keep font size bigger in my newer videos. Appreciate you!
Great video. Please increase the font size
Thank you, I'll make sure to to that in my next coding video đ
Kinda skimmed the video a bit.. good stuff.. but couldn't u also store string in variable A. Then instead of creating different functions, just create variable B that takes the original variable and then use .split().reverse().join() and compare if original variable A === variable B?? No for loop needed...
Thanks for watching! And yes, absolutely this is another great way to do it! There is value in both ways. Your example is a great use of built in JavaScript functions. Sometimes companies like to see the long hand version so they can gauge your skill of manipulating data. It's easy to call reverse(), but showing you can do it yourself is sometimes what gets you the job. In a coding challenge interview, I like to show how I organize code, how I work through a problem, and how I can come to a solution that shows my abilities. At the end of the day, we can all code the same thing in different ways, and I love the way you solved it.
On the 16:00 - what if you did unshift instead? You would have a reverse words I believe
Hey there!thanks so much for watching, Can you clarify what you're asking? Unshift instead of what? What's the solution you're proposing?
I'm a big supporter of different ways to accomplish the same result! So please share what your thoughts are.
â@@CodingWithKevin1 Yeah, I haven't tested but if you do this instead:
```js
for(let i = 0; input.length > i; i++) {
palendrome.unshift(input[i])
}
```
It puts the letters from the last to first, compared to push where it puts the first letter into first index
Awesome! Definitely test it, and then let us know. The wonderful thing about code is there are multiple ways to get to the same end result!
@@CodingWithKevin1 Yeah I might actually, I do like this challenge :) I haven't watched most of the video tbh, I don't wanna spoil the challenge for myself lol I just skipped though it. Always do this with these sort of challenges, and then compare :D
Are you sure this is mid-level? Seems way to easy for that. Shouldnt even an Intern be able to do this?
Hey thanks so much for watching my video! In my opinion, if you know an intern in America who can do this, please put them in touch with me so I can help them get a better job.
@@CodingWithKevin1 well i was looking for this video in order to prepare for intern interviews...
Does this mean u r hooking me up? :')
Let's chat, send me a dm on CZcams
@@einfachnurlegendar7947yeah I guess they removed that again lol just sent you a request.
const [input, setInput] = useState("");
const [display, setDisplay] = useState("");
function inputHandler(e) {
setInput(e.target.value);
}
function isPalindrome() {
let reversedArray = input.split("").reverse().join("");
if (reversedArray === input) {
setDisplay("It's Palindrome !!!");
} else {
setDisplay("No it's Not Palindrome !!!");
}
}
return (
inputHandler(e)} />
Submit
{display}
);
Mid-level? Seems very basic to me.
