Categorized request examples and articles tagged with [javascript-array-join] keyword How do I join array elements in JavaScript?
To join JavaScript array elements in a string, you can use the array.join(separator) method. The array.join() method takes an array as input and a delimiter as a parameter and returns a string where all array elements are joined into a string using the specified delimiter. By default, array elements are concatenated using a comma "," as a delimiter. The array.join() method does not modify the array. If the method is called on an empty array (the length of the array is zero), then an empty string will be returned. Any array element that has the value "undefined" or "null" will be converted to an empty string. In this JavaScript Join Array Elements into a String Example, we use the array.join() method to join all array elements in a string.
