Including an Externally Hosted Script in ReactJs

Hi everyone,

Just a quick example of how to include an externally hosted js file in a reactjs app. In index.html add your script tag as you would in a normal app:

  <head>
    <script src="https://js.prelive.promisepay.com/PromisePay.js " type="text/javascript"></script>
  </head>

Then in the file you plan to use the library you can add a const and reference it normally:

const promisepay = window.promisepay;
