My Experience of Using Vim.js

To use Vim in other computers, the official website of PortableApps has already provided users a satisfactory solution. The installation size is about 28 MB (according to the released figure). If you won't have it installed in a portable device and don't want to download and install it into a new machine each time, maybe you can try Vim.js. However, I've found it slow, when compared to a Vim program.
