严格断言模式

assert.deepStrictEqual() 的别名。

旧版断言模式

稳定性: 0 - 弃用: 改为使用 assert.deepStrictEqual() 。

测试 actual 和 expected 参数之间的深度相等。考虑使用 assert.deepStrictEqual() 代替。 assert.deepEqual() 可能产生意外的结果。

深度相等意味着子对象的可枚举"自有"属性也按照以下规则递归地评估。

History

Version	Changes
v12.0.0	The type tags are now properly compared and there are a couple minor comparison adjustments to make the check less surprising.
v9.0.0	The `Error` names and messages are now properly compared
v8.0.0	The `Set` and `Map` content is also compared
v6.4.0, v4.7.1	Typed array slices are handled correctly now.
v6.1.0, v4.5.0	Objects with circular references can be used as inputs now.
v5.10.1, v4.4.3	Handle non-`Uint8Array` typed arrays correctly.
v0.1.21	Added in: v0.1.21

Strict assertion mode

An alias of assert.deepStrictEqual().

Legacy assertion mode

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

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