This is a memo for exchanging text containing newlines in JSON.
A line break entered in a <textarea>, for example, is represented by \n.
JSON does not support \n, but replacing \n with <br> or escaping it like \n would work.
# When you want to output to HTML file
json.text.replace(/\n/g, '<br>')
# When you really want to output as "\n"
json.text.replace(/\n/g, '\\n')
# remove \n
json.text.replace(/\n/g, '')/g is Regular expression.
You can exchange text data in a nice way.
