Create React App Officially Deprecated Amid React 19 Compatibility Issues
Create React App is officially deprecated due to React 19 issues and lack of maintenance—developers should switch to Vite or other modern alternatives.
JavaScript date format tester.
Very lightweight (~2k min & gzip) utility function for testing if the string matches the date format.
It has only one public function test
which takes 2 parameters (string
and format
|formats
) and returns true
if string matches or false
if it doesn't.
See the example below:
test('12/04', 'YYYY/MM'); // false, doesn't match
test('2012/04', 'YYYY/MM'); // true, match
You can pass multiple formats at once:
test('12/04', ['YYYY/MM', 'YYYY/MM/DD']); // false, doesn't match
test('2012/04', ['YYYY/MM', 'YYYY/MM/DD']); // true, match

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Test your code using grunt.
Also, please don't edit files in the "dist" subdirectory as they are generated via grunt. You'll find source code in the "src" subdirectory!
