What is the best way to separate a string using a comma as a delimiter and transform it into a string that resembles an array with individual string elements

I am in search of a way to transform a string, such as: "one, two, three, four" into a string like:

"["one", "two", "three", "four"]"

I have been attempting to devise a solution that addresses most scenarios, but so far, I have not been successful. The approach I have taken thus far is as follows:

 var splitString = <mystring>.split(', ');
 var stringWithQuotes = `"` + stringSplit.join(`", "`) + `"`;

However, if the input is formatted as "one,two,three,four" (without spaces), the string will not be split correctly. Additionally, the square brackets are missing from the output as well.

Do you have any suggestions for how this issue can be resolved?

To enable optional whitespace between tokens, splitting on a regular expression is the way to go.

const str = "one,two,thee,four";
const parts = str.split(/,\s*/);
const result = '["' + parts.join('", "') + '"]';
console.log(result);

Here is the solution I came up with:

    var sentence = "apple, banana, cherry, date";
    var array = sentence.split(", ");
    var json = JSON.stringify(array);
    console.log(json);

This code will output the string '["apple", "banana", "cherry", "date"]'
