javascript - Remove whitespace from text while preserving newlines -

-

i want sanitize poetry text, below sample: (used code tag better see hidden characters):

მეორდება ისტორია,
დღევანდელს ჰგავს გარდასული, რახან ბევრი გვიცხოვრია, ნუთუ დგება დასსარული?!

არა! არ თქვა დავბერდითო, ნუ მაჯერებ, რაც არ მჯერა, არ მწამს სიტყვა ავბედითი, რომ ჩამძახონ ათასჯერაც!

i tried with:

function sanitize(txt) {     txt = txt.replace(/\s+\n/g, "\n");     return txt; }

it works removes new lines between paragraphs. want remove white space end , start each line , leave new lines as presented

i know it'd easy solve i'm stuck

thanks

\s matches spaces including line breaks.

txt.replace(/^ +| +$/gm, "");

this removes 1 or more horizontal spaces (except tabs) present @ start or @ end of line.
