For me its based on my SM role experience and types of roles available for the Devs Ive worked with. I'm learning TypeScript for React Apps as it's compatible with Office365 sites like SharePoint and Teams.
Mine is the HTML, CSS, PHP and SQL bundle. I love being able to create a system or applet and see how things are going to look and build backwards to the function. I created an entire ergonomics platform with bootstrap and a bunch of custom css so style things out how I needed them to be, then started adding in PHP and SQL to add in the functionality and ecosystem I was looking to build.
Yes, I started programming with html like you. In general, this is the simplest and easiest programming language I have ever learned.
But after learning these three languages, I learned Java, C ++, asp and sql, and after that I learned php.
