This post is focused on how to convert array into comma separated string in javascript. We will use how to convert array into comma separated string in javascript. I explained simply step by step create a comma separated list from an array in javascript. This article goes in detailed on convert array to comma separated string javascript.
There are several ways to convert an array to a comma-separated string in JavaScript:
1. Using the join() method: The join() method joins all elements of an array into a string, separated by a specified separator (in this case, a comma).
Example 1:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

</head>
<body>
</body>
<script type="text/javascript">
const arr = [1, 2, 3];
const str = arr.join(',');
console.log(str); // Output: "1,2,3"
</script>
</html>
2. Using the toString() method: The toString() method converts an array to a string by concatenating all its elements separated by commas.
Example 2:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>How To Convert Array to Comma Separated String JavaScript? - NiceSnippets.Com</title>
</head>
<body>
</body>
<script type="text/javascript">
const arr = [1, 2, 3];
const str = arr.toString();
console.log(str); // Output: "1,2,3"
</script>
</html>
3. Using a loop: You can also use a for loop to iterate over the array and concatenate its elements with commas.
Example 3:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>How To Convert Array to Comma Separated String JavaScript? - NiceSnippets.Com</title>
</head>
<body>
</body>
<script type="text/javascript">
const arr = [1, 2, 3];
let str = '';
for (let i = 0; i < arr.length; i++) {
if (i === arr.length - 1) {
str += arr[i];
} else {
str += arr[i] + ',';
}
}
console.log(str); // Output: "1,2,3"
</script>
</html>
#JavaScript
