Common Error Types

Built-in error classes

JavaScript has several built-in error types:

TypeError: Wrong type (calling non-function)
ReferenceError: Undefined variable
SyntaxError: Invalid code structure
RangeError: Number out of valid range

undefinedVar;        // ReferenceError
null.method();       // TypeError

Each type tells you what category of problem occurred.
