Feature Request: Ability to filter out fields in an array of objects.

[toinetoine]

Ability to filter out fields in an array of objects.

    var ash = { 
        name: 'Ash Catch Em', 
        badges: [
            {name: 'Otoshi', year: 2001}
            {name: 'Mismagius', year: 2003}
            {name: 'Nando', year: 1999}
        ]
    }

    const filter = require('filter-anything');
    console.log(filter.omit(ash, ['badges.year']));
    /*
    name: 'Ash Catch Em', 
        badges: [
            {name: 'Otoshi'}
            {name: 'Mismagius'}
            {name: 'Nando'}
        ]
    }
    */

I guess syntax would have to be different, since omitting 'badges.year' would remove {badges: {year: ___} in addition to {badges: [{year: ___}, ... ] }. Maybe ['badges].year' to specify that badges is an array of objects you want to omit the field year from?

Hi
thanks for your issue!

This is a use case that's too specific for me to support in my opinion.

If we agree on some syntax for this, it will always be a syntax that's not understandable from just looking at it, so I want to avoid this.

On the other hand, if you simply manually write what you want to achieve with the functions provided on arrays, it's easy to support this and when another developer looks at is there is no chance for any confusion.

Here is how you manually do this:

const { omit } = require('filter-anything')

const ash = { 
	name: 'Ash Catch Em', 
	badges: [
		{name: 'Otoshi', year: 2001}
		{name: 'Mismagius', year: 2003}
		{name: 'Nando', year: 1999}
	]
}

const ashFilteredBadges = {
	...ash,
	badges: ash.badges.filter(badge => omit(badge, ['year']))
}

will equal to

{
	name: 'Ash Catch Em', 
	badges: [
		{name: 'Otoshi'}
		{name: 'Mismagius'}
		{name: 'Nando'}
	]
}
