Is an Array extension class which adds asynchronous functions to Array as well as firing events on 'remove', 'add' or 'change'
var EventedArray = require('array-events');
var myArray = new EventedArray();
change : fired any time an element is added or removed
add : fired any time an element is added
remove : fired any time an element is removed
EventedArrays are also Emitters but have an expanded syntax from extended-emitter and the additional .when() call.
myArray.on('change', function(event){ });
myArray.once('change', function(event){ });
myArray.off('change', function(event){ });
myArray.emit('change'[, arguments]);
forEachEmission : execute serially
myArray.forEachEmission(function(item, index, done){
somethingAsynchronous(function(){
done();
});
}, function(){
//we're all done!
});
forAllEmissions : execute all jobs in parallel
myArray.forAllEmissions(function(item, index, done){
somethingAsynchronous(function(){
done();
});
}, function(){
//we're all done!
});
forAllEmissionsInPool : execute all jobs in parallel up to a maximum #, then queue for later
myArray.forAllEmissionsInPool(poolSize, function(item, index, done){
somethingAsynchronous(function(){
done();
});
}, function(){
//we're all done!
});
contains : does the array contain this element?
new EventedArray(['dog', 'cat', 'mouse']).contains('cat') //returns true;
combine : generate a new array that is the union of the provided arrays
new EventedArray(['dog', 'cat']).combine(['mouse']) //returns a new array ['dog', 'cat', 'mouse'];
erase : generate a new array without the member provided
new EventedArray(['dog', 'cat', 'mouse']).erase('cat') //returns a new array ['dog', 'mouse'];
EventedArray.is : is the provided object an instance of EventedArray
EventedArray.is(new EventedArray()); //returns true
EventedArray.is([]) //returns false
