How can I make a default parameter in Typescript?

How can I make a Typescript function parameter have a default value ?

I have this code:

modalSubmit = (autoSave) => {

    var self = this;
    self.stateService.network('Submitting');
    self.modal.resetDisabled = true;
    self.modal.submitDisabled = true;
    autoSave = autoSave || false;

Is there a way with Typescript that I can make autoSave default to false if it's not set ?

Just for information, if you are wondering how you should check for a value in pure JS: 

autoSave = autoSave !== undefined ? autoSave : false;

Of course typescript does it for you.
