my secret mission with Perchance is to get people interested in coding with a smooth, fun learning-curve

Seems like it worked!

I do web dev on a daily basis, and I tend to think of HTML as “formatted” data.

A database has data in it, but it’s in a format of columns and rows, like a spreadsheet.

My application fetches that raw data and uses code to manipulate it - it can inspect it, rewrite it, combine it with other data from other places, validate it against rules - all sorts of stuff.

Since my app is a web app, all that code is designed to use the data formatted in columns and rows from the database, and use it to generate new data in HTML format to send to the browser.

Technically, writing HTML for a browser is a form of programming - it’s a set of instructions that tell the browser how to display the data in the HTML. It’s not considered programming in a professional sense, though, as HTML doesn’t get, send, change, or process data. Its purpose is as a format for data to be sent and read by something else (the browser).
