import { getByKey } from "ast-get-values-by-key";

// GETTER // ======

// returns "object-path" notation paths where arrays use dots: assert.deepEqual( getByKey( { parsed: [ { tag: "html", }, ], }, "tag", // value to search for ), [{ val: "html", path: "parsed.0.tag" }], );

// SETTER // ======

assert.deepEqual( getByKey( { parsed: [ { tag: "html", }, ], foo: { tag: null, }, bar: { tag: null, }, }, "tag", // value to search for [123, 456], // pot of values to pick from (one result not enough) ), { parsed: [ { tag: 123, }, ], foo: { tag: 456, }, bar: { tag: null, // value pot was depleted and there was nothing left to put here }, }, );``
