Anubhav Yadav got First up vote on Answer on Stack Exchange
Anubhav Yadav posted an answer on Stack Exchange regarding a sorting issue on JavaScript.

While Anubhav himself was searching for the answer, as more often he needs this sorting function for his Trading Algorithm efforts, he used to forget after a while and have to search it again and again. This time, he landed on Stack Exchange and found that no body has in fact put a correct answer. So it was moment of shining for him and he used his Programming and English ability to frame a simple answer which can be easily understood and helpful to others.
This answer was posted in April of 2019 but in April of 2019 Anubhav got an up vote for it. This shows the rigorous nature of stack exchange where not anybody can validate an answer. Only those with 50+ reputation do it, which solidifies the effort of Anubhav.
