<p>I've found <code>String.fromCharCode(13, 10)</code> helpful when using view engines. 
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/fromCharCode</p>

<p>This creates a string with the actual newline characters in it and so forces the view engine to output a newline rather than an escaped version. Eg: Using NodeJS EJS view engine - This is a simple example in which any \n should be replaced:</p>

<p>viewHelper.js</p>

<pre><code>exports.replaceNewline = function(input) {
    var newline = String.fromCharCode(13, 10);
    return input.replaceAll('\\n', newline);
}
</code></pre>

<p>EJS</p>

<pre><code><textarea><%- viewHelper.replaceNewline("Blah\nblah\nblah") %>

replaceAll:

String.prototype.replaceAll = function (find, replace) {
    var result = this;
    do {
        var split = result.split(find);
        result = split.join(replace);
    } while (split.length > 1);
    return result;
};
