Why halibut? It's just a random name 😂

1. JS Quiz

MON - What is NodeJS. A runtime environment for JS
WED -Compliance in Web3. How to enforce, in an open economy, sanctions and blocking funding of terrorists, and thorough code review? Memory leak from useEffect and setInterval. this in traditional vs arrow functions
THU - “display: none = None at all. Others = still takes space.”, Reading layout (eg. offsetHeight) forces the browser to "flush the pipeline" to give you a correct value.

MON	TUE	WED	THU	FRI
-	2	2 (live)	3	4 (live)

MON - K-th Smallest in Lexicographical Order Hard Trie question. Interesting to observe this data structure being used on numbers. I was only exposed to using it on letters (i.e word search) before.
TUE - Maximum Difference Between Even and Odd Frequency I Easy Hashmap question. Revised "Three Sum" Two Pointer question!
WED - Maximum Difference Between Even and Odd Frequency II Bitmask, Prefix Sum. Skipped the usual suspect (bitmask) part, but did 670 / 690 cases with the latter!
THU - Maximum Difference Between Adjacent Elements in a Circular Array Easy Array question
FRI - Minimize the Maximum Difference of Pairs very interesting application of Binary Search, Medium.
SAT - Maximum Difference by Remapping a Digit. An Easy Greedy question but edge cases threw me off a little.
SUN - Max Difference You Can Get From Changing an Integer Medium Greedy question.

MON - another 7 questions on Edabit (to be honest, it's more like Leetcode than JS questions like flatten array, but let's take it for today)
TUE - Data Merging and Holy Grail.
WED - Flatten in actual setting! and Throttle
THU - Flatten, Debounce, and Deep Clone
FRI - (live) diff 2 objects
