What is Array.join() method in JavaScript?
In JavaScript, the join()
method is used to create and return a new string by concatenating all the elements of an array, separated by a specified separator string. If no separator is provided, a comma (,
) is used as the default separator.
Syntax:
array.join(separator)
Parameter:
array
: The array whose elements will be joined into a string.separator
(optional): A string used to separate each element in the resulting string. If omitted, a comma (,
) is used as the separator.
Example: Here, the join()
method is called on the fruits
array with ", "
as the separator. This joins all the elements of the array into a single string, with each element separated by ", "
. The resulting string "apple, banana, orange"
is stored in the result
variable.
Javascript
const fruits = [ "apple" , "banana" , "orange" ]; const result = fruits.join( ", " ); console.log(result); |
Output
apple, banana, orange
