How to iterate over a map in pug

I have a map that I am passing to pug on my server but I am unable to iterate over the key value pairs in the map in order to render the data in the map. I have tried simplifying the map down but still can't get it to work.

router.get('url', middlware(),(req,res)=>{ let renderData = {}; renderData.test = new Map([["1","one"],["2","two"]]); res.render('template', renderData); }) 

template:

block content .container .mt-3.whiteBG each item in test p here is some text 

In the simplified version I can't even get plain text to render, let alone access the values of the map within the iteration. I am able to access the values if I do something like this p #{test.get("1")} Are maps just not iterable in Pug? If not is there a way for me to convert my map into an array/object that Pug can iterate through?

Pug will support iteration over ES6 collections in the next release. Until then, you can convert the Map to an object using Object.fromEntries():

renderData.test = Object.fromEntries(renderData.test);
