Tests:
Filter-Map
const ids = array .filter(item => item.name === 'Me') .map(item => item.id);
Reduce-Push
const ids = array .reduce((ids, item) => { if (item.name === 'Me') { ids.push(item.id); } return ids; }, []);
Reduce-Concat
const ids = array .reduce((ids, item) => { if (item.name === 'Me') { return ids.concat(item.id); } return ids; }, []);
Reduce-Spread
const ids = array .reduce((ids, item) => { if (item.name === 'Me') { return [...ids,item.id]; } return ids; }, []);
ForOf-Push
const ids = []; for (const item of array) { if (item.name === 'Me') { ids.push(item.id); } }
