2019:Day 02

Day 2 requires the use of BigInt which is added to Javascript in ES2020 and I didn't include a polyfill. This limits the solution to Javascript engines with BigInt support

2018:Day 14

Day 14 is fast but needs more memory to complete. Run node with 4GB of heap space: node --max_old_space_size=4096 index.js
