Answers for "js compare 2 object if same"

javascript compare two arrays of objects get same elements

var result = result1.filter(function (o1) {
    return result2.some(function (o2) {
        return o1.id === o2.id; // return the ones with equal id
   });
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));

check if two objects are equal javascript

function checkObjEqual(obj1,obj2){
for(let key in obj1){
  if(!(key in obj2 )) return false;
  if(obj1[key]!==obj2[key])return false;
}
return true;
}

console.log(checkObjEqual({maroon:'#800000',purple :'#800080'},{purple :'#800080',maroon:'#800000'})) //true
