Filter array of objects with another array of objects

With Ecma script 6.

const myArrayFiltered = myArray.filter( el => {
  return myfilter.some( f => {
    return f.userid === el.userid && f.projectid === el.projectid;
  });
});

Function:

const filterObjectArray = (arr, filterArr) => (
    arr.filter( el =>
        filterArr.some( f =>
            f.userid === el.userid && f.projectid === el.projectid
        )
    )
);

console.log(filterObjectArray(myArray, myFilter))

In response to Andy answer above, which I believe should be marked now as answer., if you are looking for exact opposite behavior, use every with negation, something like this.

const result = masterData.filter(ad => 
             filterData.every(fd => fd.userid !== md.userid));

result contains all masterData except filterData.

var filtered = [];

for(var arr in myArray){
   for(var filter in myFilter){
       if(myArray[arr].userid == myFilter[filter].userid && myArray[arr].projectid == myFilter[filter].projectid){
          filtered.push(myArray[arr].userid);
         }
   }
}
console.log(filtered);

You can put a couple of array methods to use here - filter and some. They're available in all recent browsers, and there are polyfills available for the older browsers.

const myArray = [{ userid: "100", projectid: "10", rowid: "0" }, { userid: "101", projectid: "11", rowid: "1"}, { userid: "102", projectid: "12", rowid: "2" }, { userid: "103", projectid: "13", rowid: "3" }, { userid: "101", projectid: "10", rowid: "4" }];
const myFilter = [{ userid: "101", projectid: "11" }, { userid: "102", projectid: "12" }, { userid: "103",  projectid: "11"}];

const myArrayFiltered = myArray.filter((el) => {
  return myFilter.some((f) => {
    return f.userid === el.userid && f.projectid === el.projectid;
  });
});

console.log(myArrayFiltered);
