What is the output produced by the following code: const settings = { username: 'lydiahallie', level: 19, health: 90 }; const data = JSON.stringify(settings, ['level', 'health']); console.log(data);?

What is the output produced by the following code: const settings = { username: 'lydiahallie', level: 19, health: 90 }; const data = JSON.stringify(settings, ['level', 'health']); console.log(data);?

• A. {"level":19, "health":90}
• B. {"username": "lydiahallie"}
• C. ["level", "health"]
• D. {"username": "lydiahallie", "level":19, "health":90}

Answer: (A)

In this scenario, the code utilizes `JSON.stringify` with a second argument, which is an array of strings that specifies the properties to be included in the resulting JSON string. The `settings` object contains three properties: `username`, `level`, and `health`. However, the second argument instructs `JSON.stringify` to only include the specified properties, which are `level` and `health`. As a result, the output produced by this code is a JSON string that only includes the `level` and `health` properties with their corresponding values. This leads to the final output being `{"level":19, "health":90}`, which is the correct answer. The other options do not accurately reflect the behavior of the `JSON.stringify` function when provided with a filtering array. The incorrect options either include properties not specified in the array or do not represent the structure of the resulting JSON as defined by the provided instructions.
