Collection collectors are not always correct

[devbridie]

For functions that cause mutations, the current approach of translating $("a").hide() to document.querySelectorAll("a").forEach(e => e.style.display = "none"); is possible, but functions that return values will not be transformed as expected.

Consider the following cases:

• const a = $("a").css("font-size"); - The documentation specifies that the value of the first element in the collection is returned.
• const t = $("a").matches(".active"); - The documentation specifies that the value should be true if one of the elements matches the selector.
• There could be more collectors.

Therefore, the current forEach approach does not work for all cases.

Each transformation should be augmented with a transformation that should be used to collect the results of an application to a collection.
