queryLogic.isSubset(a, b)

Returns true if a is a subset of b. Equal sets are considered subsets of each other. In set theory, subset is represented by A ⊆ B.

import {QueryLogic} from "can";
const queryLogic = new QueryLogic();

const filter = queryLogic.isSubset({filter: {type: "critical"}}, {});
console.log( filter ); //-> true

const emptyObject = queryLogic.isSubset({}, {});
console.log( emptyObject ); //-> true
