Match

[christianchown]

Hello. Someone just creating an overlapping library - https://github.com/danielpa9708/ts-types-utils - that has 3 types. 2 are duplicates:

• ArgsType === ParamTypes
• Assign === Overwrite

Match - https://github.com/danielpa9708/ts-types-utils#match looks quite useful

type FunctionProperties<T> = Match<T, Function>;

is easier to formulate than

type FunctionPropNames<T> = { [K in keyof T]: T[K] extends Function ? K : never }[keyof T];
type FunctionProperties<T> = Pick<T, FunctionPropNames<T>>;

Of course, just lifting it from https://github.com/danielpa9708/ts-types-utils wouldn't be cool, but maybe reach out to the author to consolidate?

Edit

It looks like @danielpa9708's ArgsType could be an improvement on ParamTypes - it looks to be able to work for any number of parameters, and ArgsType[N] === ParamN for any N....

I'm ok with it, if this package has more popularity it should be here too. Also I recommend adding some keywords to the package.json, I couldn't find this package

Actually I think ArgsType is already in the standard libraries as Parameter, I will be deprecating it from my module, maybe you should too
