javascript - Removing new lines except when new line preceded by double space -

i want remove new lines text, except when sentence ends in double space (i'm using javascript).

this:

this test.

should turn this:

this test.

but this:

this  //there double space here a//but not here test.

should turn this:

this test.

my approach far: can replace multiple spaces followed new line single new line:

var doublespacenewline = new regexp(/(\s){2,}\n/g); test = text.replace(doublespacenewline, '\n');

but how remove newlines, without removing 1 want remain?

i prefer remove new lines except newlines preceded double or more spaces, replace double space + newline single new line.

i need regex match \s+ except when (\s){2,}\n. can't seem able combine both.

text = text.replace("  \n", '****************');  text = text.replace("\n", ' ');  text = text.replace('****************', "  \n");

is you're after? doesn't use regex, bit simpler of procedure.
