Using Method Chaining With The Revealing Module Pattern In JavaScript
// Create an instance of our cache and set some keys. Notice that the [new] operator
// is optional since the SimpleCache (and revealing module pattern) doesn't use
// prototypical inheritance. And, we can use method-chaining to set the cache keys.
var cache = SimpleCache()
.set( "foo", "Bar" )
.set( "hello", "world" )
.set( "beep", "boop" )
;
console.log( cache.has( "beep" ) );
