Unexpected Token Syntax Error
An unexpected token syntax error occurs when a programming language parser encounters a symbol or character that does not fit the expected syntax rules of the language. This can happen when a misplaced or incorrect character is used, leading to a breakdown in the code's structure and causing the parser to be unable to correctly interpret the code. These errors can be frustrating for developers as they can be difficult to locate and fix, often requiring careful examination of the code to identify the issue.
