Map [1]

Operation	Time Complexity
Access	O(log n)
Search	O(log n)
Insertion	O(n) for <= 32 elements, O(log n) for > 32 elements [2]
Deletion	O(n) for <= 32 elements, O(log n) for > 32 elements

Thanks to the original blog post: https://equimper.com/blog/how-to-setup-tailwindcss-in-phoenix-1.4

1. Install tailwindcss and postcss-loader from npm:

cd assets
npm i --save-dev tailwindcss postcss-loader postcss-import

2. Initialize tailwind (still in assets directory)
