var numbers=[[1,2,3,4,5],[6,2,3,5,5],[9,8,3,4,9]]

How to find the index value of the above two dimensional array?

Answer 1

Try like this

var searchItem=2;
numbers.forEach(function(parentItem,parentIndex){
  parentItem.forEach(function(childItem,childIndex){
     if(childItem===searchItem){
        console.log(parentIndex);
        console.log(childIndex);            
     }     
 })

});
