I'm using a hashchange listener in my React component. The listener is mounted in componentDidMount() via onhashchange rather than using addEventListener() through the commented line. Is there a difference between the two?

componentDidMount:function(){
    onhashchange=this.checkHash
    //window.addEventListener("hashchange", this.checkHash);
},

It's calling a custom function checkHash().

How do I unmount the listener?

Is it the same as:

componentWillUnmount:function(){        
    window.removeEventListener("hashchange", this.checkHash);
}

Thanks.
