2 sourcesA 2013 spreadsheet formula language would look pretty similar to what we see now. The format is simple and relatively easy for people to understand.
If I were able to change it, I may consider adding a left hand side to the formulas (A3=A1+A2 rather than just =A1+A2), which seems verbose but completely obviates the need for the special array formula type (e.g. `{=A1:A2 * B1:B2}`, which would be naturally expressed as C1:C2=A1:A2 * B1:B2).

If you want to explore JS in excel formulae further, there are people trying to implement the formula space in JS: https://github.com/sutoiku/formula.js
BTW: if your goal is to attack the spreadsheet space by innovating on formulas, you are probably barking up the wr
