Support arrays

[bwendt-mylo]

I'm often needing to drill into arrays within nested objects and have paths like the following:

values.conditions[1].operator

This PR adds the ability for dlv to accept these types of paths, doing a greedy split on word boundaries instead of splitting on dot. Minimal increase in size to 132b.

@developit Any chance you could take a look at this PR? It would be very helpful!

Just use values.conditions.1.operator

[developit]

Indeed - any reason values.conditions.1.operator doesn't work for you @bwendt-mylo? You can also pass an Array: dlv(obj, ['values', 'conditions', 1, 'operator']).

I do use the existing methods, and they work fine. This would just be a convenience thing when using libraries like redux-form where you get dot-and-bracket paths like:

contact.billing.address[2].phones[1].areaCode

[developit]

Gotcha. The solution of splitting on non-word characters is really clever, but it breaks for a bunch of property names:

dlv(obj, 'foo.some property') // should be equivalent to obj.foo['some property']

Are you open to modifications to the PR to add more flexibility/account for the edge cases or do you not feel like it's worth the added complexity at this point?

@developit @ajoslin The more I've tried to find a suitable pattern/workaround for this problem the more I realize that's terribly hard and won't stay tiny. Thanks for entertaining the idea.
