title: How to properly use jquery-mask-plugin in typescript?
body: <p>I have an ASP.NET Core MVC project that needs to have masks on some inputs.</p>
  <p>I installed the <a href="https://www.npmjs.com/package/jquery-mask-plugin" rel="nofollow noreferrer">jquery-mask-plugin</a> using the instructions for Typescript, so just used this in the console:</p>
  <pre><code>npm install --save-dev @types/jquery-mask-plugin
  </code></pre>
  <p>When I try to use the code</p>
  <pre><code>$(&quot;#inputID&quot;).mask('AAAAAAAAAA');
  </code></pre>
  <p>in the app, I get this error in devtools when running the project:</p>
  <blockquote>
  <p>Uncaught TypeError: $(...).mask is not a function</p>
  </blockquote>
  <p>Am I using this wrong because it is typescript? My version is 4.1.3</p>
