[JavaScript] Remove all Newlines From String

We can make use of the replace() method to replace all the newlines from a String. Let us take a look at it by an example.

Example 1:

const egStr = 'Hello \
and \
Welcome \
to \
Code2care!';

const strWithoutNewLines = egStr.replace(/[\r\n]/gm, '');
console.log(strWithoutNewLines);

Let's see another example where we have newline characters (EOL) within our string.

Example 2:

const egStr = "Today \n is a good \n day!\n";
const strWithoutNewLines = egStr.replace(/[\r\n]/gm, '');
console.log(strWithoutNewLines);

Note: As the newline character can be a \n, \r or a \r\n, it is better to have a Regex that matches and removes all of such characters.

EOL Character	Description	Usage
\n	Newline character (Line Feed)	Used in Unix and Linux Systems.
\r	Carriage Return	Used in older Macintosh Systems.
\r\n	Carriage Return + Newline (CRLF)	Used in Windows and DOS Environments.
