Formatting data in array

Question

I have an array incident which is of the following format :-

var incident = 
[ [1, ['a', 'b', 'c'] ],
 [2, ['d', 'e'] ],
 [3, ['f', 'g', 'h'] ],
 [4, ['i'] ]
];

Now i want to extract data out of this array and format it something like this.

data = [ ["a", "b", "c"], ["d", "e"], ["f", "g", "h"], "i" ];

I tried formatting but no success. If anyone could help me out in this. Thanks a lot in advance.

Answer 1

You could use Array#map and check if the element has a length of one for a single element, otherwise return the array.

var incident = [[1, ['a', 'b', 'c']], [2, ['d', 'e']], [3, ['f', 'g', 'h']], [4, ['i']]],
 data = incident.map(function (a) {
 return a[1].length === 1 ? a[1][0] : a[1];
 });
console.log(data);

.as-console-wrapper { max-height: 100% !important; top: 0; }
