Difference Between git log and git reflog

git log and git reflog are both commands in Git, but they serve different purposes.

git log:
- The git log command is used to display the commit history of a repository.
- It shows a list of commits, starting with the most recent one, and includes information such as the commit hash, author, date, and commit message.
- By default, it displays the commit history for the current branch.
Example:
```
git log
```
git reflog:
- The git reflog command, on the other hand, is used to display the reference logs.
- Reference logs are a history of where the HEAD and branch references have pointed to in the past.
- It includes not only the commit history but also any changes in branch pointers, such as branch creations, checkouts, merges, and rebases.
- git reflog is useful for recovering lost commits or branches.
Example:
```
git reflog
```

In summary, while git log shows the commit history of a branch, git reflog shows a more detailed history of reference changes, which includes movements of the HEAD and branch references. The git reflog can be particularly helpful for recovering from accidental changes or if you need to revisit a previous state of your repository.
