Declaration or statement expected.javascript

This error message typically occurs when there is a syntax error in your JavaScript code.

It means that the JavaScript interpreter has encountered a line of code where it was expecting a declaration or statement, but instead found something else.

Some common reasons for this error include:
- Forgetting to include a semicolon at the end of a line
- Mismatched brackets or parenthesis
- Misspelling a keyword or variable name
- Using reserved words as variable names

To fix this error, carefully review your code and make sure all syntax is correct and all statements and declarations are complete.
