How to limit the number of dropzone.js files uploaded?

Question

Depending on the use case, how do I constrain the number of files that dropzone.js will allow?

For example, I might need to only allow 1, 2, or 4 files uploaded.

Alternative solution that worked really well for me:

init: function() {
    this.on("addedfile", function(event) {
        while (this.files.length > this.options.maxFiles) {
            this.removeFile(this.files[0]);
        }
    });
}
