Transform differents element into array in only one array

Question

I'm trying to display multiple elements in a single array. (See example)

But I do not know how to do it ...

Thanks for your help

I display my script:

****Du code******

var color = [];
var risk = []; 
if(Operational.length == group.name.length){
  color = "green";
  risk = "Operational";
  console.log(group.name);
  // toto
  // tata
  // titi
}

if(Test.length > 0){
  color = "";
  risk = "";
}

 if(PartialOutage.length > 0){
   color = "orange"
   risk = "Partial";
 }

 if(MajorOutage.length > 0){
   color = "red";
   risk = "Major ";
 }
  var Group = new Array(color,risk,group.name);     
   Groups.push(Group);
   Groups.sort();
 }
});          
console.log(Groups);
}

**** Du code *****

Actual result :

[ [ 'green', 'Operational', 'toto' ],
[ 'green', 'Operational', 'tata' ],
[ 'green', 'Operational', 'titi' ],
[ 'orange', 'Partial', 'test' ],
[ 'red', 'Major ', 'test2' ] ]

Expected result :

[ [ 'green', 'Operational', 'toto,tata,titi' ],
[ 'orange', 'Partial', 'test' ],
[ 'red', 'Major ', 'test2' ] ]

check this out.Recreate the final array value as you expected format using Array#reduce

1. Push the first one child array into New Array a
2. Then loop the each b child array with newly created array a
3. Used forloop for break the loop
4. if child array value exist in new array a .Then Merge two array and filter the duplicate //Check the comments in snippet

 var a = [ ['green', 'Operational', 'toto'], ['green', 'Operational', 'tata'], ['green', 'Operational', 'titi'], ['orange', 'Partial', 'test'], ['red', 'Major ', 'test2'] ]; a = a.reduce(function(a, b) { for (var i = 0; i <= b.length; i++) { var brk = false; var check = true; if (a.length > 0) { a.forEach(function(k, ind) { if (k.indexOf(b[i]) > -1) { //if contains same arg k = k.concat(b); //join two array var j = k.filter((l,n)=> k.filter(m=> m == l).length == 1).filter(o=>o) a[ind] = k.filter((l, n) => k.indexOf(l) != n); // filter duplicate a[ind].push(j.join(',')) brk = true; //then break the statement check = true; } else { check = false; //its not contain any arg direct push child into new array } }) if (brk) { break; } if (!check) { a.push(b) } } else { a.push(b); } } return a // recreated new array return }, []); console.log(a);
