How To Join All Elements Of An Array In Javascript

The JavaScript Array class provides a method called join that allows you to concatenate all elements of an array into a single string. By default this method separates the elements by a comma.

var primes = [0, 1, 2, 3, 5, 7, 11]; var primeStr = primes.join(); // > "0,1,2,3,5,7,11"

An optional second parameter to the join method is the separator you wish to use. Suppose you have an array of words that you want to join into a sentence (separated by spaces).

var words = ['The', 'rain', 'in', 'Spain', 'stays', 'mainly', 'in', 'the', 'plain']; var sentence = words.join(' '); // > "The rain in Spain stays mainly in the plain"
