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.

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

Good stuff, many things to learn

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

Geeting something new everytime,

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.

Thank you so much for spending time in mock interviews and sharing with us. Wonderful session as always ☺️

One more Gem from Chakde frontend ❤❤❤

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

Really good choice of questions. Learnt a lot

very knowledgeable

Great interview and top candidate 🚀

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

Really nice learning something different from you always new things, please add time stamps if its possible?

amazing session. So much to learn. Thanks a lot, Chirag for the take up this series.

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.

❤

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.

Love from kerala ❤

Good stuff. Chiraj could you please upload the mock interview for 2 years experienced candidates.

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?

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?

Please make videos for react interview as well

Hi Chirag sir, can you suggest some resources where we can practice these kind of questions to prepare for our interview.

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.

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 ❤

Hi Chirag, Can you please suggest some resource where we can practice these type of question?

Asking Just out of curiosity Being an engineering manager at MS, how much you need to code in daily basis?

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!

How should junior developer should answer in interview and explain our approach to the interviewer.

can you make video on how senior developer code and review code of junior developer

can i know where can i get practice problems like those in the video

Sir, what about backend mock interview 😅

I want to give the mock interview. But I don't think I can pass! 😂

what online compiler are you using to code?

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
