javascript operator ":! 0" – what does that mean in this assignment statement?

Not an expert in javascript.

What does this ternary looking operator in this assignment mean?

var E,I,w={localhost:!0,"":!0,"":!0};
function p(e,t){
  var n="";
 for(var r in t)n+="".concat(r,": ").concat(t[r],"; ");

var E,I,w={localhost:!0,"":!0,"":!0};
function O(e){
  var t=w[document.location.hostname];
  if(e)return new i.default({APIUrl:e,setCookie:!t});
  var n=localStorage.getItem("myUrl");
  return n&&u.default.setSiteURL(n),null
return new i.default({setCookie:!t})
