Two dimensional array is not being printed using javascript

Question

The following is a two dimensional array, I just need to print it, but when I loop inside of it I get [object object] or undefined

const myarra = function(){
    return [
        [
          { "dayOfMonth" : 1, "dayOfWeek" : "Fri", "event" : "" },
          { "dayOfMonth" : 2, "dayOfWeek" : "Sat", "event" : "" }
        ]
    ];
};

`console.log(output);` return gives you variables for assignment — Matthew Ciaramitaro, Sep 20 '17 at 19:06

This way you can trace each elements in your array.

Also you can use JSON.stringify(arrayVariable) method if you just want to print that array using console.log(JSON.stringify(arrayVariable)) this code.

 function myfunction(){
   var array=[[{"dayOfMonth":1,"dayOfWeek":"Fri","event":""},
         {"dayOfMonth":2,"dayOfWeek":"Sat","event":""}]];
    
    for(var i=0;i<array.length;i++){
     for(var j=0;j<array[i].length;j++){
    console.log(array[i][j]);
     }
    }
 };
  
  myfunction();

can you tell me how to print it with JSON.stringify(arrayVariable)? – Sep 20 '17 at 19:16
`JSON.stringify()` will Convert a JavaScript value into a string and it will output that string in console using `console.log(JSON.stringify(arrrayvariable))`. For more info about JSON.stringify() refer the [link](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify). – Jino Shaji Sep 20 '17 at 19:22

You can use JSON.stringify()

const myarra = function(){
  return [[{"dayOfMonth":1,"dayOfWeek":"Fri","event":""},
         {"dayOfMonth":2,"dayOfWeek":"Sat","event":""}]];
  };

JSON.stringify(myarra())

because it first creates this array and then writes

"[[{"dayOfMonth":1,"dayOfWeek":"Fri","event":""},
     {"dayOfMonth":2,"dayOfWeek":"Sat","event":""}]];"
