严格断言模式

assert.deepStrictEqual() 的别名。

遗留断言模式

稳定性： 3 - 传统：请改用 assert.deepStrictEqual()。

对 actual 和 expected 参数进行深度相等性测试。考虑改用 assert.deepStrictEqual()。assert.deepEqual() 可能会有意想不到的结果。

🌐 Tests for deep equality between the actual and expected parameters. Consider using assert.deepStrictEqual() instead. assert.deepEqual() can have surprising results.

“深度相等”意味着子对象的可枚举“自身”属性也会按照以下规则递归地进行评估。

🌐 Deep equality means that the enumerable "own" properties of child objects are also recursively evaluated by the following rules.
