[SOLVED] push more than one elements at same index in array

push more than one elements at same index in array

how to push more than one element at one index of a array in javascript?

like i have

arr1["2018-05-20","2018-05-21"];
arr2[5,4];

i want resulted 4th array to be like:

arr4[["2018-05-20",5],["2018-05-21",4]];

tried pushing like this:

arr1.push("2018-05-20","2018-05-21");
arr1.push(5,4);

and then finally as:

arr4.push(arr1);

But the result is not as expected. Please someone help.

Actually i want to use this in zingChart as :

Options Data Create an options object, and add a values array of arrays.

Calendar Values In each array, provide the calendar dates with corresponding number values in the following format.

 options: {
  values: [
    ['YYYY-MM-DD', val1],
    ['YYYY-MM-DD', val2],
    ...,
    ['YYYY-MM-DD', valN]
  ]
}

Solution

Assuming the you want a multidimensional array, you can put all the input variables into an array. Use reduce and forEach to group the array based on index.

let arr1 = ["2018-05-20","2018-05-21"];
let arr2 = [5,4];

let arr4 = [arr1, arr2].reduce((c, v) => {
  v.forEach((o, i) => {
    c[i] = c[i] || [];
    c[i].push(o);
  });
  return c;
}, []);

console.log(arr4);
