Javascript array join new line
|
From this question, this ... Show is one way to split a string, but how do I join it back with newlines? Also, I wonder if I is say linux which uses whichever newline character, then switch to windows, won't my web app break? The newlines become not recognized? Or maybe the browser does some conversion?
