Next
Because asynchronous calls suck out your brain without a proper async handler. This one is just 4 lines yet it solves a huge issue.
Install
npm install nextjs
How it works?
- Create a
Next Instance
: var next = new Next(2, finish)
- Then you call
next()
as many times as you specified in the count
. In this example it is 2.
- After
next
was called 2 times, the finish
function will be called.
Example
// Include
var Next = require('nextjs');
// CREATE a Next Instance
var next = new Next(2, finish);
// Log Start
console.log('start');
// Will happen after 5 seconds passed
setTimeout(function(){ console.log('A'); next(); }, 5000);
// Will happen after 2 seconds passed
setTimeout(function(){ console.log('B'); next(); }, 2000);
// Will happen in the end after 5 seconds passed
function finish(){ console.log('finished'); }
// output result
// 0 second => start
// 2 second => B
// 5 second => A
// 5 second => finished
