I need to somehow arrange the data below to a certain format like below:
const data: {} = [
{ emotion: 3, intensity: 1 },
{ emotion: 5, intensity: 2 },
{ emotion: 3, intensity: 1 },
{ emotion: 3, intensity: 2 },
]
const dataone = _.groupBy(data, 'emotion')
const entries: any = Object.entries(dataone)
console.log(entries)
To this format:
[{emotion: 3, 1: 2, 2: 1, total: 3},
{emotion: 5, 1: 0, 2: 1, total: 1}]
Would appreciate it if you could provide any help or link to some similar questions.
You could group and update the values.
const
data = [{ emotion: 3, intensity: 1 }, { emotion: 5, intensity: 2 }, { emotion: 3, intensity: 1 }, { emotion: 3, intensity: 2 }],
result = Object.values(data.reduce((r, { emotion, intensity }) => {
r[emotion] ??= { 1: 0, 2: 0, emotion, total: 0 };
r[emotion][intensity]++;
r[emotion].total++;
return r;
}, {}));
console.log(result);.as-console-wrapper { max-height: 100% !important; top: 0; }
