Tips for utilizing Javascript Arquero in a web browser

Hello, I am just starting out in the world of JavaScript so please be patient with me. I recently discovered the Arquero JavaScript library and I would like to incorporate it into a standalone HTML file. After reading through the documentation available on their website, it seems like this should be feasible. They provide a brief code example (shown below) that is primarily designed for use within a Node.js environment, but I am having trouble adapting it for use in a web browser. Can anyone guide me on how to structure this script in a basic HTML format?

// <script src="https://cdn.jsdelivr.net/npm/arquero@latest"></script> // This references the Arquero library

import { all, desc, op, table } from 'arquero';

// Average hours of sunshine per month, sourced from https://usclimatedata.com/.
const dt = table({
  'Seattle': [69,108,178,207,253,268,312,281,221,142,72,52],
  'Chicago': [135,136,187,215,281,311,318,283,226,193,113,106],
  'San Francisco': [165,182,251,281,314,330,300,272,267,243,189,156]
});

// Sorted differences between Seattle and Chicago.
// Table expressions use arrow function syntax.
dt.derive({
    month: d => op.row_number(),
    diff:  d => d.Seattle - d.Chicago
  })
  .select('month', 'diff')
  .orderby(desc('diff'))
  .print();

Answer №1

The documentation states:

Arquero will be brought into the aq global object

To utilize the functions, you must prefix them with aq.

// Average hours of sunshine per month, from https://usclimatedata.com/.
const dt = aq.table({
  'Seattle': [69,108,178,207,253,268,312,281,221,142,72,52],
  'Chicago': [135,136,187,215,281,311,318,283,226,193,113,106],
  'San Francisco': [165,182,251,281,314,330,300,272,267,243,189,156]
});

// Sorted differences between Seattle and Chicago.
// Table expressions use arrow function syntax.
dt.derive({
    month: d => aq.op.row_number(),
    diff:  d => d.Seattle - d.Chicago
  })
  .select('month', 'diff')
  .orderby(aq.desc('diff'))
  .print();
<script src="https://cdn.jsdelivr.net/npm/arquero@latest"></script>
