I have this object:
const memorized = [
{
verses: [1, 2, 3, 4, 5],
when: '2022 Jan 14'
},
{
verses: [6, 7, 8, 9]
when: '2022 Jan 15'
},
{
verses: [10, 11, 12, 13, 14, 15]
when: '2022 Jan 16'
},
...
]
No need to push when you map - that is wasting an array
EITHER push in a forEach or just flatMap the array
const memorized = [ { verses: [1, 2, 3, 4, 5], when: '2022 Jan 14' }, { verses: [6, 7, 8, 9], when: '2022 Jan 15' }, { verses: [10, 11, 12, 13, 14, 15], when: '2022 Jan 16' } ]; const total_verses = memorized.flatMap(({ verses }) => verses) console.log(total_verses);
