Recently, I started to touch git. Learning to Git diff is always confusing. Git diff compares the difference between the two files. After searching the net on the net, finally found Le answer. There are two cases, one is when there are files in staging area, and the other is no files in staging area. (1) When there are no files in staging area, git diff compare

In practice, by using Git diff to calculate the number of code changes, there is a need to just count certain types of files (files with special suffix names/extensions), such as: Only the variables for files in the current git repo. java,. xml,. c,. cpp. There are two ways to make git count according to the file suffix name and to count the eligible files in each subdirectory. 1. Use the ' *.java ' and ' *.xml ' directly, if your git version is new

General overview diff [Options] source file destination file Describe In the simplest case, diff compares the contents of two files (source and destination files). The file name can be-text read by the standard input device. As a special case, diff--Compare a standard input to its own copy if the source file is a directory and the destination file is not (a di

The most magical part of react is the virtual DOM, and its efficient diff algorithm. This allows us to "refresh" the entire page at any time without worrying about performance issues and "without scruple", by the virtual DOM to ensure that the actual DOM operation is performed only on the truly changing parts of the interface. React is transparent enough in this section, and in real-world development we don't have to worry about how virtual DOM works.
