The phrase “lines of code” (LOC) is a metric generally used to evaluate a software program or codebase according to its size. It is a general identifier taken by adding up the number of lines of code used to write a program. LOC is used in various ways to assess a project, and there is a debate on how effective this measurement is.
Lines of code also has some variations such as "source lines of code" (SLOC), which is also used to enumerate a codebase. Part of the use of LOC involves a “philosophy of code,” that is, whether it is better to have a large codebase or a small one, or whether it is better to have created x lines of code than to have cut x lines of code from a program. LOC is often used in these kinds of arguments, where developers and other related personnel talk about whether “bigger is better” or whether a software codebase should “go on a diet.”
