What is a parse error?

A parse error is an error that occurs when a computer program cannot understand or interpret the code that has been written. This type of error typically occurs during the process of parsing, which is the process of analyzing a string of symbols or characters in a language and determining its grammatical structure.

Parse errors can occur for a variety of reasons, such as syntax errors, missing or misplaced punctuation, or using incorrect data types. These errors can prevent the program from running correctly or at all, and they must be fixed before the code can be successfully executed.

Common examples of parse errors include missing parentheses, mismatched curly braces, and using reserved keywords incorrectly. Debugging tools and syntax checkers can help identify parse errors and suggest ways to fix them.
