5 ms·Show HN: Constaints-based spreadsheet prototype in Elm7 points by adnanh 9y agofiatjaf 9y agoWhat does "constraints-based" mean?hawkice 9y agoThe example is a good one -- the third cell is set to 300 AND a1 + a2. Then, a1 is set to 51, which automatically sets a2 to 249. At no point was a2 given a formula, it is just constrained by the formulas in other cells.fiatjaf 9y agoOh, that's bizarre, but I like it.
