How to write this typescript function with generic arguments in a variable function(store the function in a variable)?
function identity<T>(arg: T): T {
return arg;
}
I tried this and it complains Cannot find name 'React'
const identity = <T>(arg: T): T => {
return arg;
}
Assuming you're referring to the Cannot find name 'React'. error, that's because typescript tries to parse <T>.. as a React element. You can add a comma after the generic parameter to prevent this: <T> ~> <T,>
const identity = <T,>(arg: T): T => {
return arg;
}
Alternatively, you can add a dummy extends clause, e.g. <T extends {}>, but <T,> is the cleanest solution.
