Setting the property name into brackets give the ability to evaluate its value as an expression. Thus custom property names can be created:

}
console.log(a.foo1) // print 1

Using the object EventSource from the client side in javascript ! So it allows to stream updates from a server.

}

sayHello(undefined) // print "Hello World!" in the console

Such as : aRandomDate.toLocaleDateString(window.navigator.languages[0])
