UIElement list
Enable JavaScript errors
When set to True, the JavaScript code editor shows errors for JavaScript and JSX files. Errors appear in the Error List with a (JS) prefix. Viewing these errors is useful if you're working with code that you didn't write and you don't intend to fix syntax errors.
Show errors as warnings
When set to True, JavaScript errors are shown as warnings instead of errors in the Error List.
