# JavaScript Errors
 
JavaScript errors are runtime errors thrown by the language itself, such as `TypeError`, `RangeError`, and `ReferenceError`. These occur when code tries to perform an invalid operation, like calling a method on `undefined`. They can be caught using try/catch blocks or error event listeners.
