JavaScript for Competitive Programming

on YouTube ↗20m

" summary

JavaScript runs common contest tasks about 5x slower than C/C++ (example: 25,000th prime) and its Number type overflows factorials beyond ~170 → Infinity, so a string-based big-integer using digit-by-digit multiplication is built and validated on HackerRank test cases. Memory pain shows when 1,000 doctors produce ~7,000 JSON objects for weekly slots, so availability is packed into 24-bit binary integers per day, drastically cutting objects and RAM and improving lookup and transmission performance.
