在 javascript 中具有数值属性的数组和对象是否相等？

Question

谁能给我解释一下为什么以下是正确的：

let foo = { 
    A: [ 1, 2 ] 
}
let bar = {
   "A": {
      "0": "1",
      "1": "2"
   }
}
assert.deepEqual(foo, bar);

Answer 1

正如the documentation所说：

Only enumerable "own" properties are considered. The assert.deepEqual() implementation does not test the [[Prototype]] of objects or enumerable own Symbol properties. For such checks, consider using assert.deepStrictEqual() instead.

assert.deepStrictEqual() 函数也检查原型，

assert.deepStrictEqual(foo, bar);

将 return 错误。
