This Parameter Exists For Historical Reasons

javascript-memes, legacy-code-memes, api-design-memes, browser-api-memes, backward-compatibility-memes | ProgrammerHumor.io

The JavaScript pushState() function has an unused parameter that literally does nothing but can't be removed because... backward compatibility! 🤦‍♂️

It's like that one useless function parameter that's been in your codebase for 5 years and everyone's too scared to remove it because "something might break." The documentation even admits it with a straight face: "This parameter exists for historical reasons, and cannot be omitted."

The red scribbles perfectly capture every developer's reaction: "??? WTF" - which is basically the official technical term for legacy code maintenance.

Content r just like to interject for a moment. What you're referring to as Linux, is in fact, GNULinux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Mary computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called "Linux," and many of its users are not aware that it is basically the GN system, developed by the GNU Project. There redly is a Linux, and these people are using it, but it is just a part of the system they use.
