subquery(query, ...params)

Given a query object, returns an object with only a subset of the parameters in it. Similar to lodash's pick. A similar function that takes a list of parameters to exclude is subqueryOmit.

Arguments

1. query (Object): The query parameters object, mapping from query param to encoded value.
2. ...params (String): The list of query parameters to keep in the returned result. These values should match a subset of the keys in query.

Returns

(type): Returns query with only the keys defined in params.

Examples

subquery({ a: 'one', b: 'two', c: 'three' }, 'a', 'c');
// === { a: 'one', c: 'three' }
