Get the amount of free memory in bytes (as integer): os.freemem()

The os module has the freemem() method to return information on the free memory available in the system. The freemem() function returns an integer and it represents the bytes. If you need megabytes or kilobytes you have to convert it.

import { freemem } from 'os'
const mem = freemem()
console.log('The amount of free memory is %d bytes', mem)
