Hi Chirag,I have 1.5 years of experience. Just one week ago, an interviewer asked me the same first question (auto retry api). At that time, I wasn’t able to answer that question😢. I wish I had found this video a little earlier😅. Thank you, Chirag, always love your videos.
🎉🎉🎉🎉
Awesome. More videos to come. Keep learning, keep sharing 🚀
❤️❤️
which company and can you please tell me some more intresting questions asked
Amazing work @Chirag. Even though I have 13 years of experience and have learned a lot from you, Thanks, bro
Best interview series on internet. This video made my day. Thanks Chirag sir once again for this gem
Thanks a ton ❤️
Geeting something new everytime,
Good stuff, many things to learn
Glad you liked it. Keep watching, keep sharing 🚀
Hey , the question levels are just awesome.. I can't even imagine that this type of questions can be asked in interviews... Will follow this series to be updated
Awesome. Keep learning, keep sharing 🚀
Chirag, I have following you since a while, I would say you are doing a great job. 👍👍
The Problem statements you come up with are very unique and organised, I am learning a lot from this series.
I was expecting someone from same experience level to come for this series.
I wish I would be there some day on this series as well 😂, Just Kidding.
For Pavan, I would say, He should be pushed to next Round. 👍
keep up the great work.
Thanks for the feedback ❣️
Thank you so much for spending time in mock interviews and sharing with us.
Wonderful session as always ☺️
Glad you enjoyed it! ❣️
One more Gem from Chakde frontend ❤❤❤
Keep watching, keep sharing 🚀 Many more to come ❤️
I think Pawan was updating the timestamp at the time of getting the data/key, that's why the timestamps at the end are the same (same problem as the setAsyncData being passed 0 for timeout value in setTimeout).
Keep the series going, really helpful
Keep learning, keep sharing 🚀
Really good choice of questions. Learnt a lot
Glad to hear! ❣️
very knowledgeable
Great interview and top candidate 🚀
Awesome ❣️ Many more to come. Keep watching, keep sharing 🚀
Yooo!!! Best js interview of the whole Chakde frontend interview series.
My solution:
//LRU cache automatic cache clear
// approach 1: which came to my mind at first
/*
lets have a cache array in which i'll be putting cache data
and will try to add the time when we have added it in it.
will run a auto clear cache function after certain time and it will check
sort the array based on time, the items which are added.
will remove least recently used
*/
let count = 0;
let cache = new Array(5);
cache.fill({ item: "2", time: 10 });
function addToCache(data) {
let currentTime = Date.now();
cache.push({ item: data, time: currentTime + count });
count++;
}
function LRU(data) {
cache.sort((a, b) => a - b);
let leastRecentlyUsed = cache[0];
console.log("leastRecentlyUsed", leastRecentlyUsed);
cache.shift();
addToCache(data);
}
function pushDataToCache(data) {
if (cache.length !== 5) {
addToCache(data);
}
else {
LRU(data);
}
}
pushDataToCache(40);
pushDataToCache(50);
pushDataToCache(60);
pushDataToCache(30);
pushDataToCache(10);
pushDataToCache(1);
pushDataToCache(50);
console.log(cache);
function getValueFromCache(data){
let finding = cache.find(item => item.item === data);
if(!finding){
console.log(data, "Not found");
return;
}
console.log(data, "Yes item found",finding);
}
getValueFromCache(50);
getValueFromCache(40);
Thank you, Chirag Sir
Great you liked it ❤️
Really nice learning something different from you always new things, please add time stamps if its possible?
Noted. 👍
amazing session. So much to learn. Thanks a lot, Chirag for the take up this series.
Glad you liked it❤️
What is the code editor that you are using Chirag ?
Thanks Sirji...❤🎉

Hi Chirag, I have 5+ years of experience in UI development with Tech skills: HTML5,CSS3 Bootstrap,Tailwind CSS,Responsive Design, Media Queries. I have knowledge on Javascript and Vuejs framework just i want to improve deep knowledge and Strong experience in Javascript and other Framework like React. I know the way how to do but coming to real time, i am facing difficulty to solve problems and logical ways. Can you suggest how can I overcome from this difficulties to solve problems in logical way.
❤
❣️
Love from kerala ❤
🥳me too
Great set of questions, Chirag. Though, I have a doubt here, Using Map would be helpfull to handle the space complexity better but how is the order insertion helpful? As in map order is only updated at the time whn the values are set for the first time so later on when we set it or last access it, order wont be updated.
❤️
Good stuff. Chiraj could you please upload the mock interview for 2 years experienced candidates.
Definitely. It's in pipeline. Will be live soon 🚀
@@engineerchirag Thanks
Hi sir my self raju .I have been completd gradution since 2018 bsc(science background).After i am prepared competative exms but could not clear the exms.i am intrested to frontend developer can i learn frontend course.your valuble suggestion sir. i am also telugu medium background student
Hi chirag , So for LRU cache question , are you expecting the solution with map & linked list?
Both are good options 😃
Please share which tool you are using for questions? First i thought it is codepen. But it is something different. Is it made by you?
DM pls
Please make videos for react interview as well
Hey watch this react interview and stay tuned more react interviews are lined up
ruclips.net/video/uHGtzBn8luI/видео.htmlsi=O24RWRLpjAbZlEm0
Hi Chirag sir, can you suggest some resources where we can practice these kind of questions to prepare for our interview.
Chakde Frontend Interviews series 😛
You bring really good question @chirag
but I will not select this man as he has 9yr of exp. and instead of making thing simple, he just make it more complicated.
btw thanks for bringing such a question which will help people to thinks in real-time when a person giving interview.
Thanks for feedback 👍
What platform you are using to write code? Btw nice and informative video, a request is, your voice echoes a lot so please if possible improve it thanks for the video ❤
Let me work on Audio quality 👍
@@engineerchiragthank you sirji btw what platform it is on which candidate is coding?
Hi Chirag, Can you please suggest some resource where we can practice these type of question?
Chakde Frontend Interviews series 😛
Asking Just out of curiosity
Being an engineering manager at MS, how much you need to code in daily basis?
I find time for coding 😃
I've had some bad experiences with object in terms of maintaining the order. If the key is something that can be sorted the object follows the sorting stuff. Really weird shit in js. new Map() is what i had solved some of the order maintaining challenges so that should work here as well.
I must say pawan's skills are top notch💯
Thanks again for bringing the best content out there Chirag!!!
❤️
Hi Chirag, would you be open to conducting a mock interview with me? I’d really appreciate your guidance and feedback. Thanks!

I want to give the mock interview. But I don't think I can pass! 😂
Fill the form.
what online compiler are you using to code?
DM pls
Great learning. One doubt, If we use a map then time complexity would still be O(n). Right? What do you think about my solution? I didn't use timestamp. Just used a queue.
class LRUCache {
constructor(size = 20) {
this.cache = {};
this.keys = [];
this.size = size;
}
#moveToMostRecentlyUsed(key) {
let indexOfKey = this.keys.indexOf(key);
while (indexOfKey < this.keys.length - 1) {
const temp = this.keys[indexOfKey];
this.keys[indexOfKey] = this.keys[indexOfKey + 1];
this.keys[indexOfKey + 1] = temp;
indexOfKey++;
}
}
set(key, data) {
if (Object.hasOwn(this.cache, key)) {
this.#moveToMostRecentlyUsed(key);
} else {
if (this.keys.length >= this.size) {
const lruKey = this.keys.shift();
delete this.cache[lruKey];
}
this.keys.push(key);
this.cache[key] = data;
}
}
get(key) {
if (!Object.hasOwn(this.cache, key)) {
return;
}
this.#moveToMostRecentlyUsed(key);
return this.cache[key];
}
delete(key) {
if (!Object.hasOwn(this.cache, key)) return;
delete this.cache[key];
this.keys.splice(this.keys.indexOf(key), 1);
}
}
/************ Test Cases **************/
const lruCache = new LRUCache((size = 3));
// lruCache.set("1", "one");
// lruCache.set("2", "two");
// lruCache.set("3", "three");
// lruCache.set("2");
// lruCache.set("4", "four");
// // lruCache.delete("4");
// console.log(lruCache.keys.at(-1));
function asyncData(key, data, time) {
setTimeout(() => {
lruCache.set(key, data);
}, time);
}
asyncData("1", "one", 0);
asyncData("2", "two", 0);
asyncData("3", "three", 0);
asyncData("4", "four", 0);
setTimeout(() => {
console.log(lruCache.keys.at(-1));
console.log(lruCache.get("2"));
console.log(lruCache.keys.at(-1));
}, 2000);
Lovey @chirag. Best of Luck
❤️
Keep the series going, really helpful
Thanks, pls help to spread this series 🙏❤️
