String To String Array With Multiple Conditions

Question

I have a bot which processes strings with given arguments. Here is what I've tried to get parameters of command:

parse: function (message, argLength) {

        var words = message.split(" ");

        words.shift(); // Don't return command name in array.

        if (words.length < argLength) // If there is not enough parameters, return null

            return null;

        else if (words.length == argLength) {   // If length is exact same, return     

            return words;

        }

        else { //Otherwise, concenate first ones till it is exact length.

            var concenateString = "";

            var length = words.length - argLength + 1;

            for (var i = 0; i < length; i++) {

                var element = words[0];

                concenateString += " " + element;

                words.shift();

            }

            words.unshift(concenateString);

            return words;

        }

    }

If there are more parameters than required, it will automatically concenate first strings since it is split by spaces. a b c with two parameters to "a b" "c" for example. But if

"

's are passed, I want to get words between

"

's, not only conceding first ones.

Before doing any business logic you could use a regex to extract anything between " or words:

var str = 'one two "three is family"'
var re = /"([^"]+)"|([a-zA-Z0-9]+)/g

console.log(
  str.match( re )
)
