Usage #
The plugin allows you to extract specific information from your data by applying Jsonata queries. Here are the three alternative ways to use it:
Alternative 1:
In this approach, you directly evaluate the Jsonata expression (jql) against the provided data.
var json = await Jsonata(jql).evaluate(data);

Alternative 2:
Here, you create a Jsonata expression object and then evaluate it against the data.
var expression = Jsonata(jql);
var json = await expression.evaluate(data);

Alternative 3:
This method involves setting the data explicitly in the Jsonata instance and then querying it with the specified expression.
var jsonata = Jsonata();
jsonata.set(data: data);
var json = await jsonata.query(jql);
