Anti-duplication by user

Hello, what can be done so that I can only match the keys, including other characters that make up the object, and not the values ​​that may be the same when accidentally entered by the user? E.g. “Key: Key:” Analogous to how it would be e.g. key: key:, Key2: :. In this case, I would like to rely mainly on the “:” character, based on which it would be possible to detect whether, for example, there is a key name after the comma and the final match would look like, for example, “key:”, or “key:, Key2:”. Or in a “key: key:, key: ,” situation, the final result would be “key:, key:”

In the future, I would like to be able to deal with situations where I want to match only 1 fragment without duplicating it when it is the same.

Firstly, welcome to the forums.

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:
