- URL Constructor: Provides initial validation, ensuring the string can be parsed as a URL.
- Regex Pattern: Adds an additional layer of validation, covering cases that the constructor might miss.
Validating URLs in JavaScript can be approached in several ways, depending on your needs. The URL
constructor is a simple and reliable method for most cases, while regular expressions and third-party libraries offer more customization and coverage. Using HTML5 input fields provides native validation for forms, and combining methods ensures robust validation in production applications.
