    assert.notDeepStrictEqual(actual, expected, message?): void
    Attributes
    actual:any
    expected:any
    message:string | Error | Function

    Tests for deep strict inequality. Opposite of assert.deepStrictEqual().

    import assert from 'node:assert/strict';
    
    assert.notDeepStrictEqual({ a: 1 }, { a: '1' });
    // OK
    const assert = require('node:assert/strict');
    
    assert.notDeepStrictEqual({ a: 1 }, { a: '1' });
    // OK

    If the values are deeply and strictly equal, an AssertionError is thrown with a message property set equal to the value of the message parameter. If the message parameter is undefined, a default error message is assigned. If the message parameter is an instance of Error then it will be thrown instead of the AssertionError.
