title: Why I can't do this: ${someValue} in JavaScript / Typescript?
body: <p>I have an issue. JavaScript do not recognize code inside curly braces:</p>
  <pre><code>let a = 'John'; let s = 'Hello ${a}'; // output: 'Hello ${a}' instead of 'Hello John'
  </code></pre>
  <p>I have updated Typescript to latest version: <code>npm install typescript@latest</code></p>
