${} '

Question

I am trying to learn React and I want to understand the ins and outs of everything in this sample project.

  const siteTitle = get(site, 'title')
  title = title ? `${title} | ${siteTitle}` : siteTitle

Im assuming its comparing the main site title to individual post titles but I cant find anything online about what " /developer.mozilla.orgen-USdocsWebJavaScriptReferenceTemplate_literals。
