Stop writing utility classes. Utility classes are a sign that you are writing procedural code. You should avoid them. Instead, write a real object model. For example, an email is not a String... It's an Email. Gautier - 🤘

I don’t write utility classes I write utility functions 👌

Everyone is getting ahead with AI. You should be too. Summarize documents, craft emails, and generate custom content instantly with this powerful tool. It's like having ChatGPT tailored for your job. Try it for free.

Probably a good use of extension types for Email to implement String and also still provide validate methods.

In my opinion another approach is to use a validation library like Acanthis that will still remove the need for a utility class, while providing validation and parsing of the object. Everything is just a line of code string().email()

You didn’t give a concrete reason why your approach is better? Same validation everywhere? I don’t think that’s guaranteed any more than that a user imports the same util class everywhere. 🤔

.isEmail

Ohhh I like this

Nice

it's not an email until after it's validated. it's a wannabe

It doesn't add any value modeling the email as a different class instead of just leaving it by default as a string. You're using unnecessary resources just to wrap a simple string to a class just to make it appear as an object. You only need to validate it and that's it.(just my 2 cents)
