@varunknair1231 2 года назад

Your explanations are so spot on! I've been asking similar questions when I conduct interviews for technical rounds and if anyone of them just goes through your video for interview prep would be more than enough to atleast have the basics of js down. You should definitely continue making such videos. Oh and thanks for the jsv9000 link never knew about it, im really glad RU-vid's algorithm suggested your content! Subscribed!!

I always thought caching was something very complicated and never tried it. But it was as simple as storing data in an object. Also, never thought about using recursion in a react component itself. I learnt something new. Thank you so much. Please continue the frontend interview series.

@christian_vega 2 года назад

adding the optional context will not help in the memoized example if you want to pass in an existing cache because you're checking the cache that was passed by closure, not the cache that's being passed by "this" (eg. the context). you can verify this by changing fn.call(...) to simply fn(...args) - the cache still works.

It was really one of the best interview experience i am ever seen.. You have explained each and every in detail.. Please come up with more interview experience may be of your friend or colleague .. One doubt -- May be we don't need isFolder variable.. because every folder object has items as one property so we can use that ..like -- if(explorer.items) {do something} else {do other} ..

@rohanpaul2504 Год назад

Hey great job !! One doubt though, the question 21:17 for the folder structure instead of handling of handling the tree on CSS side, wouldn't it be better to handle the collapse and expand on js side by keeping track of expanded or collapsed items, because through your approach u are always looping over the children elements and then hiding /showing them based on the click.

@adityatripathi1904 2 года назад

Instead of making the folder hierarchy nested in json, you can try index approach which a lot of NoSql DBs use. It has O(1) access time and a flat structure unlike the nesting. Great video keep it up!

@RoadsideCoder 2 года назад

Hey, Thanks for sharing this info!

@aniruddhpandya5999 2 года назад

By Index approach, do you mean you'll use the two json objects, one being the index, the other for data and then embed the data ids in the index?

@adityatripathi1904 2 года назад

@@aniruddhpandya5999 I was implying to use a map or a linear JSON with key as “level” of folder structure and value being all the files/folders in it. For eg. { 0: [Folder1, Folder2], //root 1: [{fileName: [folderItsPresentInFrom0…] } Yes the approach is bit unpolished but should work and will have advantages over nested approach in rendering operations and loading operations. For eg. we can totally not load content inside folders unless the user clicks on them, reducing the overhead.

In an interview setup it is not easy to code what you think! Just for the interest of the larger audience, at line#15, 31:37: explorer.items && explorer.items.map(exp => .......) would have also done the job I guess instead of going for an if-else? Good content and thanks for sharing this :)

@rohit3221 2 года назад

Hey. Thanks for sharing. This is quite informative and helpful. Although for the Q:5 - Infinte currying, there's a bug in the code. If we pass 0 as a number - curry(5)(0)(2)(); - The code will break. Since 0 is falsy in nature. it's gonna return the sum instead of the inner function. So when we call the returned value with param 2, we'll get an exception.
