In C#, I could check if any of the nested List collection has a value. Example of such structure [Check a List<List[]> contains a value using Linq][1]
List<int> a= new List<int>(){ 2, 2, 3, 4, 5};
List<int> b= new List<int>() { 2, 2, 2, 6 };
List<List<int>[]> c = new List<List<int>[]>();
c.Add(new[]{a,b});
// checking if the value is in any of the collections. for example, this will result to 2
var result = c.SelectMany(x => x).SelectMany(x => x).Any(p => p == 2);
but since I'm exploring the LINQ capabilities in node js , I decided to extend this to an Array of Arrays
var data= [[2, 2, 3, 4, 5],[2, 2, 2, 6], [9], [13, 1,1,90]];
var LINQ = require('node-linq').LINQ;
var resultI=new LINQ(data).Any(function(row)
{
return checkElement(row);
});
console.log(resultI);
function checkElement(array)
{
for(var i = 0 ; i< array.length; i++)
{
if(array[i]== 19){
return true;
}
}
}
Note: I installed the LINQ module using
npm install https://github.com/wearefractal/node-linq/tarball/master
Can this be improved? please any suggestions will be quite appreciated.
