There are several types of errors in JavaScript, including syntax errors, runtime errors, and logical errors.
Syntax errors occur when the JavaScript engine encounters code that does not conform to the language syntax rules.
These errors are usually detected by the JavaScript engine during the parsing phase, before the code is executed.
Runtime errors occur when the JavaScript engine encounters an error while executing the code, such as referencing an undefined variable or calling a non-existent function.
These errors can often be detected using browser developer tools or debugging tools.
Logical errors occur when the code does not produce the expected result, even though it may be syntactically correct and free of runtime errors.
These errors are often the most difficult to diagnose and fix, as they require a thorough understanding of the code's logic.
Overall, understanding the different types of errors in JavaScript is important for writing robust and error-free code.
