Numerous websites utilize the lightweight, object-oriented programming language JavaScript (js) to script their webpages. If you don’t know how to convert a comma separated string into an array in Javascript, please refer to some of the solutions we give below.

To convert a comma separated string to array in JavaScript

What can we do to convert a comma separated string into an array in Javascript? Let’s read two following methods, they will help you.

Use the split() method

The first way that you can try to convert a comma separated string into an array in JavaScript is to use the split() method. This solution relies on an extractor to partition a sequence. And to distinguish strings in the case, a comma is present; delimiters will be described as commas

Syntax: string.split(separator, limit)

Sample code

orgStr = "Mo, Tu, We, Th, Fr, Sa, Su";
newArr = originalString.split(', ');           

Result:

String: "Mo, Tu, We, Th, Fr, Sa, Su"
Array: Mo, Tu, We, Th, Fr, Sa, Su

Now with this solution, you can convert a comma separated string into an array in JavaScript.

Use the slice() method

This solution will iterate over every single character in the string and check for commas. A previous index variable will track the first character of the following string. Then, the slice() method is applied to eliminate the part of the previous index string and the existing position of the comma. Then the middle string above will be pushed to a new array. The process will repeat for the total length of the string. And the array containing all the strings that be split is the final array.

Syntax: string.slice(start,end)

Code example

orgStr = "Mo, Tu, We, Th, Fr, Sa, Su";
newArr = [];

// index of end of the last string
let preIndex = 0;

for (i = 0; i < orgStr.length; i++) {
     if (orgStr[i] == ', ') {
          // split the string by the comma
          separated = orgStr.slice(preIndex, i);

          newArr.push(separated);
          preIndex = i + 1;
     }
}

// push the last string into the array
newArr.push(orgStr.slice(preIndex, i));

Result:

String: "Mo, Tu, We, Th, Fr, Sa, Su"
Array: Mo, Tu, We, Th, Fr, Sa, Su
