string

Given a string

'1.2.3.4.5'

I would like to get this output

'1.2345'

I wrote this

function process( input ) {
    var index = input.indexOf( '.' );

    if ( index ) {
        input = input.substr( 0, index + 1 ) + 
                input.slice( index ).replace( /\./g, '' );
    }

    return input;
}

Live demo: http://jsfiddle.net/EDTNK/

It works but I was hoping for a slightly more elegant solution...
