js compares whether two object arrays are the same

1. js compares whether two object arrays are exactly the same

let obj1 = [{"id" : 1, "name" : "xiaoMing"}];
let obj2 = [{"id" : 1, "name" : "xiaoMing"}];
var isEqualN = JSON.stringify(obj1) === JSON.stringify(obj2);
console.log(isEqualN);//true

let obj1 = [{"id" : 1, "name" : "xiaoMing"}];
let obj2 = [{"id" : 1, "name" : "xiaoMi"}];
var isEqualN = JSON.stringify(obj1) === JSON.stringify(obj2);
console.log(isEqualN);//false
