Javascript try…catch…else…finally like Python, Java, Ruby, etc

Question

How can Javascript duplicate the four-part try-catch-else-finally execution model that other languages support?

Answer 1

I know the question is old and answers has already given but I think that my answer is the simplest to get an "else" in javascripts try-catch-block.

var error = null;
try {
    /*Protected-block*/
} catch ( catchedError ) {
    error = catchedError; //necessary to make it available in finally-block
} finally {
    if ( error ) {
        /*Handler-block*/
        /*e.g. console.log( 'error: ' + error.message );*/
    } else {
        /*Else-block*/
    }
    /*Final-block*/
}
