Resource Management with 'using'

This package allows you to use C# like syntax for resource management.

const {Resource, using} = require('use-resource')

console.log('Creating resource')
const r = new Resource({}, async () => console.log('Disposing resource'))
console.log('Using resource')
using(r, async r => {
  const timeout = new Promise(resolve => setTimeout(() => resolve(), 1000))
  await timeout
  console.log('Working with resource')
})
