I have 2 arrays. The first contains the years like
[2021,2020,2019,2018,2017]
and the second contains number of occurrence like
[2,3,1,3,3]
I want the new array to look like this
[[2021,2],[2020,3],[2019,1],[2018,3],[2017,3]]
How to do this? Please help!
Thank you in advance.
UPDATE:
const merge = (y, o) => {
const res = [];
y.forEach((year, i) =>
res.push(`${year},${o[i]}`)
);
return res;
};
console.log(merge(allyears,farray))
I tried doing this and it works fine but the new array looks like this
["2021,3","2020,1","2019,2","2018,3","2017,3"]
How to make it look this way
[[2021,2],[2020,3],[2019,1],[2018,3],[2017,3]]
Make sure that the length of 2 arrays is equal
So we have:
const arr1 = [2021,2020,2019,2018,2017];
const arr2 = [2,3,1,3,3];
const combine = arr1.map((value, index) => ([value, arr2[index]]))
console.log(combine)P/s: There are some other solutions that you can use, but only that one above
