Get them all

Instructions

You've been attributed the task to find the main architect of the Tower of Pisa before he achieves his plans, avoiding us nowadays all those lame pictures of people pretending to stop it from falling.

You arrive at the architects' chamber to find him, but all you have in front of you is a bunch of unknown people. Step by step, with the little information you have, gather information and figure out by elimination who he is.

Launch the provided HTML file in the browser to begin your investigation.
On top of the webpage, each of the four buttons fires a function which has to return an array containing 2 arrays of HTML elements (except for the last function): the targetted people, and the others eliminated at that step - the ones previously eliminated mustn't be included.

• Write the body of the getArchitects function, which targets the architects, all corresponding to a <a> tag, and eliminates all the non-architects people.

• Write the body of the getClassical function, which targets the architects belonging to the classical class, and eliminates the non-classical architects.

• Write the body of the getActive function, which targets the classical architects who are active in their class, and eliminates the non-active classical architects.

• Write the body of the getBonannoPisano function, which targets the architect you're looking for, whose id is BonannoPisano (return only this one as a single element, not an array), and eliminates all the remaining active classical architects.

From now on, don't forget to export all the expected functions, so that they can be imported to be tested
