Array to list with quoted items

miguelele has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I need to pass a perl array, converted to a string list, to a block of JavaScript in a TT Template, to create a JavaScript array

If I use $string_to_feed_javascript = join (", ", @perl_array);

$string_to_feed_javascript contains all items separated by commas, but this breaks JavaScript syntax because each alphanumeric value must be enclosed by quotes./p>

So How can I convert the array to a string this way?
Thank you in advance

You may have heard of JSON? `useJSON::XS;` `my $string_to_feed_javascript = encode_json \@perl_array; print $string_to_feed_javascript; # string is UTF-8 encoded` [download]	[reply] [d/l] [select]

Combining a quoting construct in a map with a join seems to be less confusing to my eye. `$str = join q{, }, map qq{"$_"}, @arr;` [download] Cheers, JohnGG	[reply] [d/l]

Would this do?: `@array = qw[a list of alphanumeric values 1 2 3 4 5 6 7 8 9];; $string = '"' . join( '", "', @array ) . '"';; print $string;; "a", "list", "of", "alphanumeric", "values", "1", "2", "3", "4 +", "5", "6", "7", "8", "9"` [download] With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Thank you all!!, in this case I prefer the first solution, just using join with the quotes and the commas. Nest step will be JSON, but it will be a major update, with better skills Regards	[reply]

`$string_to_feed_javascript = do {$" = '", "'; qq{"@perl_array"}};` [download] This will do what you ask, although I expect it will break your Javascript in many interesting ways.	[reply] [d/l]
