Conclusion:

Before you start implementing these JavaScript plugins, there are some factors you should consider first. First, understand that JavaScript validation is not an effective solution for validating forms unless the user’s internet connection is stable. In order to ensure this, you must create a fallback mechanism that will operate without JavaScript. It is also important to note that many modern browsers already have built-in form validation. If a browser supports native validation tools, they will be used by default over any third party plugins.
