Error type
What went wrong?
A specific language construct was expected, but something else was provided. This might be a simple typo.
Examples
Expression expected
For example, when calling functions, trailing commas are not allowed. JavaScript will expect another argument, which can in fact be any expression.
Math.max(2, 42,); // SyntaxError: expected expression, got ')'
Correct would be omitting the comma or adding another argument:
Math.max(2, 42); Math.max(2, 42, 13 + 37);
