sample handlebar loop and helper function

loop.html

<!-- this small piece of html would be inside a larger template that's being used to draw something, such as a post -->

<ul>
  {{#each pills}} <!-- your each function called on an array that's part of your data object -->
    <li>{{getPillText this}}</li> <!-- passing the value of your array to a helper function (first argument in this template tag -->
  {{#/each}}
</ul>

loop.js

// an example of your glossary
const myPills = [
  {
    pillNo: 3,
    pillText: 'No Guns',
  },
];

// helper function gets two parameters: name of function (getPillText), and the value being passed in from template (id)
Handlebars.registerHelper('getPillText', (id) => {
  myPills.find((pill) => {
    if (pill.pillNo === id) {
      return pill.pillText;
    } return 'No text given';
  });
});
