Filter data using lodash - lodash

Question

How can filter the data with some inner attribute value.
updated_id='1234';
var result= _.map(self.list, function (item) {
// return only item.User_Info.id=updated_id
});

Answer 1

You can use the lodash#matchesProperty variant of lodash#filter to filter out objects that you need using the path of the property. The variant is in the 3rd example of the lodash#filter documentation.
var result = _.filter(self.list, ['User_Info.id', updated_id]);
var self = {
list: [
{ User_Info: { id: '4321' } },
{ User_Info: { id: '4321' } },
{ User_Info: { id: '1234' } },
{ User_Info: { id: '3214' } },
{ User_Info: { id: '2143' } }
]
};
var updated_id = '1234';
var result = _.filter(self.list, ['User_Info.id', updated_id]);
console.log(result);

Answer 2

lodash has a filter method:
const updated_id='1234';
const result= _.filter(self.list, item => item.User_Info.id === updated_id);

Answer 3

Use lodash _.filter method:
_.filter(collection, [predicate=_.identity])
Iterates over elements of collection, returning an array of all elements predicate returns truthy for. The predicate is invoked with three arguments: (value, index|key, collection).
with predicate as custom function
_.filter(myArr, function(o) {
return o.name == 'john';
});
with predicate as part of filtered object (the _.matches iteratee shorthand)
_.filter(myArr, {name: 'john'});
with predicate as [key, value] array (the _.matchesProperty iteratee shorthand.)
_.filter(myArr, ['name', 'John']);
