May I ask what are the use cases for maps like that? I don't think I have ever needed one myself.



I have situations like this quite frequently where I need to turn vars into members of an object:

    title = getTheTitle()
    img = (shouldWeGetImg) ? getImg() : "placeholder.jpg"
    body = ...
        # 8 lines of code to define body, some that reference title and img

    # this:
    obj = { title, img, body }

    # instead of:
    obj = {title: title, body: body, img: img}
