assert.deepStrictEqual(actual, expected[, message])

版本历史

版本	变更
v18.0.0	现在也比较正则表达式的 lastIndex 属性。
v9.0.0	现在比较可枚举的符号属性。
v9.0.0	现在使用 SameValueZero 比较来比较 `NaN`。
v8.5.0	现在可以正确地比较 `Error` 名称和消息。
v8.0.0	也比较 `Set` 和 `Map` 的内容。
v6.1.0	现在可以将具有循环引用的对象用作输入。
v6.4.0, v4.7.1	现在可以正确地处理类型化数组切片。
v5.10.1, v4.4.3	正确地处理非 `Uint8Array` 类型的数组。
v1.2.0	新增于: v1.2.0

测试 actual 和 expected 参数之间的深度相等。 "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。

v1.2.0	Added in: v1.2.0

actual <any>
expected <any>
message <string> | <Error>

Tests for deep equality between the actual and expected parameters. "Deep" equality means that the enumerable "own" properties of child objects are recursively evaluated also by the following rules.
