Close file after fs.readFile, nulling

fs, node.js

Solution

to close a file descriptor use this call

fs.close(fd, callback)

however since you're using `fs.readFile` which reads the entire file - it deals with opening and closing file for you, so you don't need to close anything

Problem

Just try nodejs a few days. Should i close somehow files after `fs.readFile()` ? And if yes how? Should i null or something used and needless variables for better perfomance and memory safe? Thanks.
