判断两个对象是否相同

const obj=[{a:1,b:2},{b:2,a:1},{a:1,b:2},{a:3,b:{c:11,d:4}},{a:3,b:{d:4,c:1}}
]const newArr=[...obj];
function isObject(obj){return obj!==null && typeof obj==='object';
}
function objIsEqual(obj1,obj2){if(!isObject(obj1) || !isObject(obj2)){return Object.is(obj1,obj2);}if(obj1===obj2){return true;}const keys1=Object.keys(obj1);const keys2=Object.keys(obj2);if(keys1.length!==keys2.length){return false;}for(let key of keys1){if(!keys2.includes(key)){return false;}const res=objIsEqual(obj1[key],obj2[key]);if(!res){return false;}}return true;
}
for(let i=0;i<obj.length;i++){for(let j=i+1;j<newArr.length;j++){//if(JSON.stringify(obj[i])===JSON.stringify(newArr[j])){if(objIsEqual(obj[i],newArr[j])){newArr.splice(i,1);j--;}}
}console.log(newArr)
