# RangeError

The `Napi::RangeError` class is a representation of the JavaScript `RangeError` that is
thrown when trying to pass a value as an argument to a function that does not allow
a range that includes the value.

The `Napi::RangeError` class inherits its behaviors from the `Napi::Error` class (for
more info see: [`Napi::Error`](error.md)).

For more details about error handling refer to the section titled [Error handling](error_handling.md).
