Chaining pluck() and flatten() with lodash

rated 0 times [ 125] [ 6] / answers: 1 / hits: 9539 / 10 Years ago, thu, february 20, 2014, 12:00:00

This works, but how can I chain it?...

allWeeks = _.flatten(_.pluck(dates.months, 'weeks'))

allDays  = _.flatten(_.pluck(allWeeks, 'days'))

I've tried:

allDays = _.chain(dates.months).pluck('weeks').flatten().pluck('days').flatten()

And this:

allDays = _(dates.months).pluck('weeks').flatten().pluck('days').flatten()

Instead of deleting this question out of sheer embarrassment, I will leave the answer here for any other poor schmuck out there wondering why the heck isn't my lodash chain working?!:

You must end the chain with .value()

so this:

allDays = _.chain(dates.months).pluck('weeks').flatten().pluck('days').flatten().value()

and this:

allDays = _(dates.months).pluck('weeks').flatten().pluck('days').flatten().value()
