Lodash cloneDeepWith to omit undefined

Question

I wrote a customozer function to omit the undefined values of the object with cloneDeepWith. However on the immutable return, it is not digging in recursively.

Answer 1

There's another alternative using DeepDash, which is a standalone, complementary library that offers recursive versions of Lodash functions.

Once DeepDash has been mixed in with Lodash (deepdash(_)), you can write a prune function like this:

const prune = obj => _.filterDeep(obj, (v) => !_.isUndefined(v))
