The pipe operator is awesome because you can use it to “extend” objects without messing with their prototypes.
Missing String.titleCase ? Write your own!
“hello world” |> titleCaseMissing String.titleCase ? Write your own!
“hello world” |> titleCasePersonally, I don't use classes much, but sometimes I think free functions are a little too hard to find, so I tend to experiment with the following pattern.
interface User { … }
const User = {
rename(user: User, newName: string): User { … },
getDisplayName(user: User): string { … }
}
const renke: User = { … }
console.log(User.getDisplayName(renke));
The alternative is of course having renameUser (or userRename) and getUserDisplayName (or userGetDisplayname). The prefixed version would make autocomplete easier also.
“hello world” |> titleCase (%)
I'm starting to like the F# proposal more now.
