    function func(a,b) {
        return a + b;
    }
    console.info( func(4,6) );

    // Result

Or you can invoke directly

Before

        return a + b;
    }
    console.info( anonymousMethod(4,6) );

    // Result
    10

After with JS-Lambda

    console.info( F("a,b => a + b")(4,6) );

2. Callback Examples =================

Before

    function callback( func ) {
        if( func ) func();
    }

    callback( function() { console.info('My name is Junil Um'); } );

After with JS-Lambda

    callback(  F("() => console.info('My name is Junil Um');")  );

    // Result
    My name is Junil Um

3. With jQuery ===========

Before

    var li = $("item li");

    li.each( function(i, o) {
        $(o).addClass("some");
    } );

After

    var li = $("item li");

    li.each( F("(i, o) => $(o).addClass('some');") );
