Convert returned JSON Object Properties to (lower first) camelCase

Question

I have JSON returned from an API like so:

Contacts: [{ GivenName: "Matt", FamilyName: "Berry" }]

To keep this consistent

Answer 1

If you would use lodash instead of underscore, this would do:

_.mapKeys(obj, (v, k) => _.camelCase(k))

This would convert both TitleCase and snake_case to camelCase. Note that it is not recursive though.
