For the time being, I am using Beautify over Prettier, as I like to work with 4 spaces when I tabulate my code. I recognise I can edit the finer settings within Prettier to suit my requirements if need be, but I'm also aware that there are programmers who favour the 2-space format. So far, Beautify works for me.
Nonetheless, as a software developer to be, I am forcing myself to adopt a formal style guide. Because I am learning fresh with Treehouse - amongst other online providers like freeCodeCamp and soon to be Frontend Masters - it is fair to say that I am more focused in learning good programming standards as I relearn how to code.
I know styling and formatting code is rather subjective, which is fine - but I foresee two primary reasons for using a formal style guide.
Firstly, I want to learn of the new technical standards using the latest web technologies that I am writing for. I mostly refer to the MDN (Mozilla Developer Network) to learn the new web standards - alongside W3C (The World Wide Web Consortium), but I wish to adopt a strict styling when I code through my own projects.
