Below is my array:

var array = ["abc.mp3,Lmn.mp3","pqr.mp3","ppp.mp3,ggg.mp3"];

Now I want to count length of this record but I would like to treat comma separated records as not a single record

For eg: abc.mp3, Lmn.mp3 want to to treat as 2 separated records by splitting with comma.

Expected length of array should be: 5

Is there any method which will simplify the process of counting this length instead of doing loop and then splitting each record by comma and then counting length one by one?

Reset to default

join array as string and then split string to array,then you can calculate the array length.

var array = ["abc.mp3,Lmn.mp3","pqr.mp3","ppp.mp3,ggg.mp3"].join(',').split(',');
console.log(array);
console.log(array.length);

Just a pointer, comma is the default join value. You can ignore ',' in join
@Rajesh if to ignore , in join,how to split it into array?
Join joins elements using comma itself as default.
yes,I know it,but join the array with , explicit may be let someone known clearly.

You can loop over array and create a new array that will have split values. Now you just have to do newArray.length

var array = ["abc.mp3,Lmn.mp3","pqr.mp3","ppp.mp3,ggg.mp3"];

var ret = array.reduce(function(p,c){
  return p.concat(c.split(','));
}, [])

console.log(ret.length)

Or, you can create a string and count number of commas and just add 1 to it

var array = ["abc.mp3,Lmn.mp3","pqr.mp3","ppp.mp3,ggg.mp3"];

console.log(array.join().match(/,/g).length + 1)
