pea-event ·

An event model, extended in your js app

What is this?

pea-event is a class of js that helps you manage event/listener model

class App extends PeAEvent{};

var app =new App();
app.on('click',function(date){
  console.log('app be clicked',date);
});

app.execEventAll('click',[new Date]);

Is nothing to be surprised at?

How about this:

class App extends PeAEvent{};

var app =new App();
setTimeout(function(){
  app.execEventAll('load');
},1000);

(async function(){
  await app.wait('load');
  console.log('app loaded');
}());

It's very semantic right?

pea-event can do more than this, maybe you should look at the APIs
