Convert OR split string array to individual groups of array

Question

I have an string array as follows in javsacript:

var dateArray=
["2014,01,01","2014,07,04","2014,09,01","2014,11,25"]

I want to convert this array as follows:

[2014,01,01],[2014,07,04],[2014,09,01],[2014,11,25]

Above arrays will be passed to datepicker library to disable few dates. Can anyone please help me in achieving this.

It is simple, loop through the initial array,and use a split function. Push each of the split list into another array — karthikr

@Aravind I am trying something like this. [5,6,[2014,5,9],[2014,9,6]].In the above snippet, input will be [5,6].I want to add [2014,5,9] & [2014,9,6] to it.Its type is number not string — Anand

@Anand: Though it's easy to get answers here, it won't help you learn, unless you try. While it is good to ask questions, make sure that you understand how each answer works, so you can use them in your future. Ask questions in comments if you don't understand how their answer works. Instead of saying it does not work for this input, find out why it does not work, and fix it. That way, you learn how it works. — Aravind

Use the array map function:

dateArray.map( function(x) { 
    return x.split( ',' );
} );

Quite precise! And x.split( ',' ).map(function(y) { return (+y); }); would convert the strings to numeric values.

@PeterKA I already have an array like [5,6]. I have another array like ["2014,5,6","2014,5,9"].Now I want output like [5,6,[2014,5,6],[2014,5,9]]. Output array is of type number.

@Anand—arrays are Type object. The members of the array might have a Type of number. ;-)

var dateArray=
["2014,01,01","2014,07,04","2014,09,01","2014,11,25"];

var y = dateArray.map( function(x) { 
    return x.split( ',' ).map(function(v) { return (+v); });
});

console.log( y );

UPDATE

var a = [5,6],
    b = ["2014,5,6","2014,5,9"];

  
b.forEach( function(x) { 
    a.push( x.split( ',' ).map(function(v) { return (+v); }) );
});


console.log( a );

Thanks for the help. If i run this snippet a.length gives me 3. I am expecting 4 here [5, 6 , [2014,5,6] , [2014,5,9] ].I have tried Peter but to no avail. Help is highly appreciated.

 var dateArray =
      ["2014,01,01", "2014,07,04", "2014,09,01", "2014,11,25"];
    const getdatearr = dateArray.map(x => {
      return x.split(' ')
    });
    console.log('getdarearr', getdatearr);
