I am looking to split a single array containing objects with 2 elements into two separate arrays.
After making an axios call, I received the following array:
chartdata: Array [4]
[{"total":3,"month":9},
{"total":5,"month":5},
{"total":9,"month:"2},
{"total":4,"month:"1}]
How do I extract an array of totals and an array of months from this data structure?
This solution may be considered a bit more elaborate compared to the other suggestions provided. However, it is important to note that while this method might not be the most efficient in terms of performance, it can still serve its purpose effectively. For tasks where performance plays a crucial role, opting for the map solutions suggested by others would be recommended.
// Here's an example using your array.
const chartdata = [
{"total":3,"month":9},
{"total":5,"month":5},
{"total":9,"month":2},
{"total":4,"month":1}
];
// Utilizing reduce method to extract totals and months.
const [totals, months] = chartdata.reduce((current, next) => {
return [
current[0].concat(next.total),
current[1].concat(next.month)
];
}, [[], []]);
console.log('Totals:', totals);
console.log('Months:', months);Implement the native JavaScript function map two times
outputs = data.map(function(entry){ return entry.output})
categories = data.map(function(entry){ return entry.category})
