rated 0 times [ 163] [ 2] / answers: 1 / hits: 22508 / 6 Years ago, wed, january 31, 2018, 12:00:00

I have a two dimensional array arr[cols][rows].
I want to know if the cols contains a string hello.
How can I check that using .includes(hello) method.

Please note that I am trying to check this inside a loop with counter i. So I have to do something like arr[i][0].includes(hello);

You can use array.prototype.some along with array.prototype.includes. It shoud be:

var datas= [

  [aaa, bbb],

  [ddd, eee]

];



function exists(arr, search) {

    return arr.some(row => row.includes(search));

}



console.log(exists(datas, 'ddd'));

console.log(exists(datas, 'xxx'));
