today on my RSS Feed I found this [great article](https://evotec.xyz/the-curious-case-of-null-should-be-on-the-left-side-of-equality-comparisons-psscriptanalyzer/#utm_source=rss&utm_medium=rss&utm_campaign=the-curious-case-of-null-should-be-on-the-left-side-of-equality-comparisons-psscriptanalyzerr) do you think is a good idea to add it on the best practice?
