 };

Tests:

reduce
const mockedObject = { a: { values: ['test1, test2, test3, test4'] }, b: { values: '' }, c: { values: [] } }; Object.entries(mockedObject).reduce((acc, curr) => { const [key, props] = curr; if (!props.values) return acc; return [...acc, props.values]; }, []);
flatMap
const mockedObject = { a: { values: ['test1, test2, test3, test4'] }, b: { values: '' }, c: { values: [] } }; Object.entries(mockedObject).flatMap(([key, props]) => { if (!props.values) return []; return props.values; });
