Additional information
Considering var has side effects and is generally undesirable in almost every context except when explicitly desired, the build process converting my const to var seems very strange. It also behaves differently from const so that makes this doubly strange, tho if no re-assignments are detected, it's probably fine from that angle.
However, it should be converted to let at most, not var.
