Dictionaries don’t work in such a way that you can get different keys just by adding them after eachother, this would not make sense programatically. You should therefore create a new dictionary with the keys you want. return render_template(‘index.html’, … Read more
You need one more array, instead of four separate variables. This will make it easy to pick only (the right) one of the totals to update in the inner loop.

The problem is in this line: if(p2 !== p1) { In your use of the function, p1 and p2 are arrays with x and y coordinates. Such a comparison is only true when p1 and p2 are the same array reference. This is never the case in your use cases. You need this (as is … Read more
filter iterates over all elements – you can’t stop it. I don’t think this is the right approach, you should use Array.find or Array.findIndex to probe the roles array and figure out if it has an item starting with the desired prefix. const array = { “clientName”: “xyz”, “exp”: 0, “prefUserName”: “admin-dev”, “roles”: [ “dist-users”, … Read more
