In this Tutorial we want to describe you a code that helps you to understand
array to string in JavaScript. The code create HTML Page 'Array to String'. The
page label string, text field and a insert button. On clicking a button, a
function push is invoked that include conditional operator if the value of
text field is null, this show an alert message box "Name is empty". If we
insert some value in the text field, then this value is assigned into a array. The
for loop execute and run the script till the length of i is less than array length. The
variable string store the concatenated value of array and string.
array. join( ) - This method is used to place all the element in
array into string.
document.getElementById - This is used to return the element on the
specific Id.
Finally the code display you the element of array into a string on your
supporting browser.
