The original implementation of deepGet from @Salakar here https://github.com/Salakar/deeps/blob/master/index.js works fine, but the slightly different implementation in the v3 repo returns incorrect results. The fix is trivial and I have submitted a PR #235

Example:

const a = { b: { c: 123 } }; console.log(deepGet(a, 'b/c')); // -> null, but should be 123
