RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including queuetry. Try it out:
var Q = require('queuetry')
var q = Q()
var i = 0
var res = []
// put first synchronously (before get).
q.put("a")
// get what was allready put (above).
q.getAsync(function(item) {
var j = [i++, item]
console.log(j) // [0, 'a']
res.push(j)
return true // deleted from queue.
})
// async get because no put
q.getAsync(function(item) {
var j = [i++, item]
console.log(j) // [1, 'b']
res.push(j)
return false // peeked from queue, next successfull getAsync() will delete.
})
// async get because no put
q.getAsync(function(item) {
var j = [i++, item] // [2, 'b']
console.log(j)
res.push(j)
return true
})
q.put("b") // put after get.
// Expected output =>
// [ 0, 'a' ]
// [ 1, 'b' ]
// [ 2, 'b' ]
