Description of change
This commit clarifies variables in the Filesystem docs. Prior, the documentation for fs.write() had an ambiguous remark on the parameters of offset and length.
Therefore, this commit makes explicit that the length parameter in fs.write() is used to denote the number of bytes, which is a clearer reference for its usage.
