Optional: the getStimParams function can return parameters that are not the best.

Hi, @tpronk

I'm still not sure how important this is, but I updated to receive an argument for the getStimParams function to return parameters that are not the best.

USAGE

const most_valuable_stim = jsqp.getStimParams()
const most_valuable_stim2 = jsqp.getStimParams(1) // This is the same as most_valuable_stim
const third_valuable_stim = jsqp.getStimParams(3) 

The most valuable stimulus parameters are when the entropy is at its minimum.
However, the observer may feel burdened by the response to such stimuli because the observer cannot easily determine the response.
Perhaps for that reason, another QUEST+ library also has a parameter called randomFromBestN.

If the main purpose is to deliver a stimulus that is randomly picked from a set of stimuli, maybe have getStimParams return an array? Something like this perhaps?

// Return a single stimulus
const most_valuable_stim = jsqp.getStimParams()
// Return an array with one stimulus; same stimulus as above
const most_valuable_stim = jsqp.getStimParams(1)
// Return an array with the three best stimuli
const most_valuable_stim2 = jsqp.getStimParams(3)

Thank you for your reply.

The getStimParams needs to return a single stimulus-parameter combination, not an array.

If a random value is needed, we can write as the following

const tmp = Math.round(Math.random()*10)
const stim_params = jsQuestPlus.getStimParams(tmp)

This is a bit off topic, but we should write jsQuestPlus.getStimParams, not jsqp.getStimParams. I made a mistake in my first post.
