I am trying to find out the meaning of this syntax with double colons and no matter how I google it nothing comes up. Can anyone please tell me what ::this means as in for example:

 <MenuItem style={{'width': '21rem'}} eventKey="4" onSelect={::this.handleSignOut}>Sign out</MenuItem>

I am going through some React Redux codes on gitHub and there are full of these. I have some dispatch actions but they dont work inside the handleSignOut function and I dont know if it's to do with ::this. Thanks
