Vim displays `file1.js` buffer, but it actually creates two buffers: `file1.js` buffer and `file2.js` buffer. Run `:buffers` to see all the buffers (alternatively, you can use `:ls` or `:files` too).
- `:bnext` to go to the next buffer (`:bprevious` to go to the previous buffer).

Moving between windows is like traveling two-dimensionally along X-Y axis in a Cartesian coordinate. You can move to the top, right, bottom, and left window with `Ctrl-W H/J/K/L`.
Moving between buffers is like traveling across the Z axis in a Cartesian coordinate. Imagine your buffer files lining up across the Z axis. You can traverse the Z axis one buffer at a time with `:bnext` and `:bprevious`. You can jump to any coordinate in Z axis with `:buffer filename/buffernumber`.
You can move in *three-dimensional space* by combining window and buffer movements. You can move to the top, right, bottom, or left window (X-Y navigations) with window navigations. Since each window contains buffers, you can move forward and backward (Z navigations) with buffer movements.

`vimdiff` displays two buffers side-by-side. On the left is `file1.txt` and on the right is `file2.txt`. The first differences (apples and oranges) are highlighted on both lines.
Suppose you want to make the second buffer to have apples, not oranges. To transfer the content from your current position (you're currently on `file1.txt`) to `file2.txt`, first go to the next diff with `]c` (to jump to the previous diff window, use `[c`). The cursor should be on apples now. Run `:diffput`. Both files should now have apples.

If you need to transfer the text from the other buffer (orange juice, `file2.txt`) to replace the text on the current buffer (apple juice, `file1.txt`), with your cursor still on `file1.txt` window, first go to the next diff with `]c`. Your cursor now should be on apple juice. Run `:diffget` to get the orange juice from another buffer to replace apple juice in our buffer.
