Each programmer has their own coding style, conscious or otherwise. Some people are verbose, others are terse, and some are slapdash. Style covers everything from whitespace, to how you name variables, to how common problems are solved. Having good style can not only make your code easier to read, but also less error prone. Often companies will put together a list of guidelines for style, aptly called a style guide.
Linters are incredibly useful programs, especially for novices. If you haven’t tried using one before, I highly recommend it. You’ll wonder how you ever coded without one.
