# 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).
