Error in shortcode section

[jmcdl]

Thanks for this guide. I've found it really useful. I came across a couple of small errors in the shortcodes section.

1. The updated src/index.njk example text is missing a quotation mark in the footer include

{% include "_foot.njk %}

2. The suggested addShortCode function is also missing a closing quotation mark and has some superfluous angle brackets>

eleventyConfig.addShortcode("shorttest", function(subtitle, greeting){
    return "<h2><em>"+subtitle+"></em>, "+greeting+"></h2>
});

I would imagine it would be better to use a template literal as in the 11ty guide.
