  Look at what this does with the feature - https://polymer.github.io/lit-html https://polymer.github.io/lit-html

  They're called tagged templates: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#Tagged_templates https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... Apart from the other examples, I've also seen them be used for internationalization. http://i18n-tag.kolmer.net/ http://i18n-tag.kolmer.net/

  Someone wandered in from perl5? (I say that as a person who enjoys perl)

  It can be used for escaping values for example var query = sql`select * from user where id=${id}` Similar for html, preventing injection. You just need to implement the corresponding functions. For example https://github.com/felixfbecker/node-sql-template-strings https://github.com/felixfbecker/node-sql-template-strings

    I don't see how this is better than var query = sql(`select * from user where id=${id}`);
    • naranha 8y ago
      Yes that's something the author does not explain well. sql is not a normal function but a special template "handler" with fixed parameters.

      In your example, you get the concatenated string. If you use the tags, you can access the parts.

      It's just a tiny language feature, removing the parenthesis is not the point of the template literal. FWIW, I like the way it looks for styled-components: const NameTag = styled.div` font-size: 12pt; margin: 3px; `;
    • basil-rash 8y ago
      In this case the sql function can not escape the id. If you were to use a tagged template, it could.
