When decoding JSON data, if a field is not present in the JSON, the field in the Go struct will be set to its _____ value.

  • zero-value
  • default value
  • NaN
  • undefined
When decoding JSON data in Go, if a field is not present in the JSON, the corresponding field in the Go struct will be set to its zero value. In Go, the zero value for a data type is the default value that is assigned to a variable of that type when it is declared but not explicitly initialized. Understanding this behavior is important when working with JSON decoding in Go to ensure that the program behaves as expected when JSON data is missing certain fields.
