SyntaxError: Unexpected token

This error occurs when the JavaScript engine encounters an unexpected character or symbol in the code. It could be caused by a missing or extra bracket, semicolon, or comma, or a typo in a keyword or variable name.

To fix this error, check your code for any syntax errors and make sure that all brackets and other symbols are properly paired and closed. It can also be helpful to use a code editor with syntax highlighting to identify any errors in your code.
