Fix the ‘SyntaxError: missing ) after argument list’ When Developing JavaScript Apps
To fix the ‘SyntaxError: missing ) after argument list’ when we’re developing JavaScript apps, we should make sure we have corresponding closing parentheses for each opening parentheses in our JavaScript code.
On Edge, the error message for this error is SyntaxError: Expected ')'.
And on Firefox, the error message for this error is SyntaxError: missing ) after argument list.
For instance, if we write:
console.log('PI: ' Math.PI);
then the error will be thrown because we’re missing the comma between 'PI: ' and Math.PI.
To fix this, we write:
console.log('PI: ', Math.PI);
The error will also be thrown if we have unterminated strings.
For instance, if we write:
console.log('"Java"' + 'Java' + 'Script\");
then we’ll get the error since we don’t have a closing single quote in the 'Script\" string.
To fix this, we write:
console.log('"Java"' + 'Java' + 'Script\"');
