title: Template literals syntax is not working in IE11
body: <p>The back-tick character is not recognized as a Valid Character in IE11 when using the "use strict" directive while it works in other browsers, such as Chrome. </p>
  
  <p>What is the interpretation of this behavior taking into consideration that IE11 is still widely used even among Windows 10 users??</p>
