Improve TypeScript Utility Types

[gwansikk]

Hello! I came across an interesting open-source project and wanted to share my thoughts.

In existing utility types like Omit or Pick, the Key part doesn't support auto-completion, which can be inconvenient. How about improving these utility types to enhance usability?

Below is an example of Omit. By using OmitKeyof, you can make it more convenient with auto-completion.

Thank you for sharing your idea.

I found your approach to enhancing utility types like Omit or Pick through OmitKeyof to be very practical. The idea of improving developer experience by adding auto-completion is particularly impressive.

Additionally, by incorporating auto-completion, your solution helps catch potential developer mistakes early, reducing the likelihood of typos and improving code accuracy.

Hello, @gwansikk.,

I am concerned about which naming would be most appropriate for this stricter version. I think OmitKeyof can be thought of as extracting a key like using the keyof operator, and I think its relationship with keyof may be somewhat unclear. The result is in the form of an object, but I thought it could be thought of as extracting keys excluding a specific key.

After checking the TypeScript issue, microsoft/TypeScript#30825, I think it would be better to define it as a new word rather than using the word Strict. Like Except. What do you think?

I agree. This is an extension of the Omit DX, and the name OmitKeyof isn't quite fitting. A more appropriate name is needed.

As a result of my search, I found that StrictOmit is commonly used in other libraries. So, although Strict is said to be ambiguous in terms of TypeScript issues, I think it is appropriate to use it.

I think StrictOmit, Except, and OmitByKey are suitable, but I would like to hear your opinion on which one is most suitable.

I think StrictOmit would be appropriate. It's used in other similar libraries and is widely recognized, which could make ts-typekit easier to understand or migrate to.

However, this is just my opinion. If we use the Strict prefix, it would make sense to use it for other utility types as well (e.g., StrictPick), so I suggest carefully considering this before making a decision.

I agree with your comment 👌.

When we use StrictOmit, the strict version of other built in utility types such as Extract is needed. Thank you for helpul opinion:)
