Loadash filter need to get exact match - lodash

Question

When trying to filter array using Lodash, i am getting all the element of that array. Need to get the specific array only. Please find my coding so far
var sizeList = [{
id: 1,
title: "Test1",
type: [{
name: "1.1",
present: false
}, {
name: "1.2",
present: true
}, {
name: "1.3",
present: false
}]
}, {
id: 2,
title: "Test2",
type: [{
name: "2.1",
present: false
}, {
name: "2.2",
present: true
}, {
name: "2.3",
present: false
}]
}, {
id: 3,
title: "Test3",
type: [{
name: "3.1",
present: false
}, {
name: "3.2",
present: true
}, {
name: "3.3",
present: true
}]
}],
result = _.filter(sizeList, {
type: [{
name: '3.3'
}]
});
console.log(result);
My problem is, when i filter with name:3.3 i am getting all the element in Test3 array including 3.1, 3.2 and 3.3. I need to only 3.3. Can anyone please help.

You can map the items after filtering by type, and filter the type array as well:
var sizeList = [{"id":1,"title":"Test1","type":[{"name":"1.1","present":false},{"name":"1.2","present":true},{"name":"1.3","present":false}]},{"id":2,"title":"Test2","type":[{"name":"2.1","present":false},{"name":"2.2","present":true},{"name":"2.3","present":false}]},{"id":3,"title":"Test3","type":[{"name":"3.1","present":false},{"name":"3.2","present":true},{"name":"3.3","present":true}]}];
var result = _(sizeList)
.filter({
type: [{ name: '3.3' }]
})
.map(({ type, ...o }) => ({
...o,
type: _.filter(type, { name: '3.3' })
}))
.value();
console.log(result);
