Creates a value/error pair to mimic promise behavior
npm install async-value-promiseAn AsyncValuePromise represents a value that will exist in the future. It is
similar to a Promise but does not include error boundary zoning or forced
asynchrony, for performance reasons.
This module is internally synchronous. What this means is that if a value
promise has already had resolve or reject called, any calls to then will
trigger the corresponding callback immediately. Conversely, if any callbacks
have already been attached with then before a resolve or reject occurs
they too will run immediately. This is intentional for performance reasons.
``sh`
npm install async-value-promise
`js
var pass = new AsyncValuePromise()
pass.then(name => {
console.log(hello, ${name}!)
})
pass.resolve('world')
var fail = new AsyncValuePromise()
fail.then(null, error => {
console.error(err.stack)
})
fail.reject(new Error('oops'))
