Example code from http://benalman.com/news/2010/11/immediately-invoked-function-expression/ written with JQuery and Amber Smalltalk

AmberSmalltalkLinkExperiment.st

'a' asJQuery each: [ :index :value |
    value asJQuery on: 'click' do: [ :event |
        event preventDefault.
        window alert: 'I am link #' , index
    ]
]
        

JQueryLinkExperiment.js

$('a').each(function(index, value) {
    $(value).on("click", function(event) {
        event.preventDefault();
        window.alert("I am link #" + index);
    });
});

Original JavaScript verison:

var elems = document.getElementsByTagName( 'a' );
for ( var i = 0; i < elems.length; i++ ) {
    elems[ i ].addEventListener( 'click', (function( lockedInIndex ){
        return function(e){
            e.preventDefault();
            alert( 'I am link #' + lockedInIndex );
        };
    })( i ), 'false' );
}
