- Revert ES6 changes to arithmetics.pegjs
- Use Array#forEach instead of for..of
- Don't use native Array#find & Array#findIndex
- Added util/arrays.js (find & findIndex)
- Use Function instead of eval
The PEG.js version is exported and also written into the generated parser. In both these instances the version is a separate string, which means every time the version is bumped, it has to be changed in 3 places. This commit makes it slightly less of a maintenance burden.
