let originalArray = [1, 2, 3, 4, 1, 2, 3, 4];
for(var i=0,obj={};i<originalArray.length;i++){
obj[originalArray[i]]=null
}
let noDuplicates=Object.keys(obj)

Same using .reduce()...

let myArray = [1,2,2,"hello world",4,5,5, {moo: "cow"}];
let myObject = myArray.reduce((acc, x) => {acc[x]=0; return acc}, {});
let noDuplicates = Object.keys(myObject);
