JavaScript Error Types

Common Error Types

SyntaxError    // Invalid syntax
TypeError      // Wrong type operation
ReferenceError // Undefined variable
RangeError     // Number out of range

Handling Errors

try {
  // Code
} catch (error) {
  if (error instanceof TypeError) {
    // Handle type error
  }
}

Key Takeaway

Different errors mean different problems. Use instanceof to check error type. Helps debug issues.
