javascript - Delete object from ImmutableJS List based upon property value -

what simplest way delete object list based on value of property?

i'm looking equivalent of $pull in mongodb.

my list looks simple this:

[{a: '1' , b: '1'},{a: '2' , b: '2'}] 

and i'd remove array object property a set '1'. in mongodb, i'd this:

model.update({_id: getcorrectparentobj},{ $pull: {listideletefrom: { a: '1' } } },(err, result)=>{}); 

how can same result immutablejs?

you filter immutable list:

var test = immutable.list.of(immutable.map({a: '1'}), immutable.map({a: '2'})); test = test.filter(function(item) { return item.get('a') !== '1' }); 

however, filter on non-empty list result different immutable list, may want check occurrence of {a: 1} first:

if (test.some(function(item) { return item.get('a') === '1'; })) {     test = test.filter(function(item) { return item.get('a') !== '1' }); }
