How to usearr.join() Method in Javascript
The join method in JavaScript is used to join the elements of an array into the string. Here, we can specify the separator or else by default it will take comma as the default separator.
Syntax:
array.join(optional_separator)
Example: In this example, we have used the default separator to show the converted array elements into string.
let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
let str = arr.join();
console.log(str);
Output
1,2,3,4,5,6,7,8,9,10

- Approach 1: Using arr.join() Method
- Approach 2: Using arr.toString() Method
- Approach 3: Using JSON.stringify() Method
- Approach 4: Using arr.reduce() Method
- Approach 5: Using a for loop
- Approach 6: Using Array.prototype.map()
So we will see all of the above states approaches with its implementation.
