Tests:

Reduce
const newObj = Object.values(a).reduce((newObj, val) => { if (val.url.includes('o')) { newObj.push(val.name) } return newObj; },[])
Filter/Map
const b = Object.values(a).filter(val => val.url.includes('o')).map(obj => obj.name)
Map/Filter
const c = ()=>{ let duplicates= []; Object.keys(a).map((key) => { if (a[key].url.includes('o')) { duplicates.push(a[key].name); } }); return duplicates ; }
