There are a number of Template Engines one can use when developing with Express + node.js.
However, now node.js 4.2.2 inherently supports ES6-Template-Strings:
https://developers.google.com/web/updates/2015/01/ES6-Template-Strings?hl=en#multiline-strings
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/template_strings
http://www.ecma-international.org/ecma-262/6.0/#sec-template-literal-lexical-components
In light of this inherent support for templates strings, what are the advantages of still using a template engines like ejs? Do any current template engines utilize ES6-Template-Strings? Are there any performance tests that compare Express Template Engines to straight ES6-Template-Strings?
