We have an array of objects as such
var myArr = [ {name: "john", age: 23},
{name: "john", age: 43},
{name: "jim", age: 101},
{name: "bob", age: 67} ];
how do I get the list of objects from myArr where name is john with lodash?
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']);
