is backoff pending?

[DetweilerRyan]

What is the recommended approach for checking if a backoff is currently pending? I'm currently checking the if timeoutID_ !== -1 to determine if a backoff is currently pending. I'd rather not depend on an implementation detail like backoff.timeoutID_.

The following is my use case:

var Backoff = require('backoff');

var backoff = Backoff.exponential();

// if the browser goes online then let's reset the backoff
//  to provide a better user experience when attempting to reconnect
window.addEventListener('online', function() {
    // are we currently waiting to reconnect
    const is_pending_backoff = backoff.timeoutID_ !== -1;
    // reset the backoff
    backoff.reset();
    // since resetting the backoff will cancel a
    //  pending backoff lets go ahead and trigger
    //  a new backoff
    if( is_pending_backoff ) {
        backoff.backoff();
    }
} );

Maybe adding an isPending to the api is a good idea?

Backoff.prototype.isPending = function() {
    return this.timeoutID_ != -1;
}

Thanks for a great library!

Maybe its better to go further and extend Backoff to cover cases like yours:

Backoff.prototype.softReset = function(err) {
    var isPending = this.timeoutID_ != -1;
    this.reset();
    if (isPending) this.backoff(err);
};

This, hovever, does not exclude the need for separate isPending function.
