Here's a method that I have:
getFiveObjectsFromArray(array: T[]) {
return array.slice(0, 5);
}
I've been using this method multiple times. Is there a way in TypeScript to pass a generic argument instead of using multiple types?
Also, when I try to use the parameter 'T', I encounter this error message:
"TS7006: Parameter 'T' implicitly has an 'any' type."
If you're looking to accept an Array regardless of its Type,
function gatherFiveItemsFromArray(array: unknown[]) {
return array.slice(0, 5);
}
If you prefer using Generic, Then
function gatherFiveItemsFrom<T>(array: T[]) {
return array.slice(0, 5);
}
gatherFiveItemsFrom<number>([0]);
gatherFiveItemsFrom<string>(["hello"]);
gatherFiveItemsFrom<string>([0]); // displays error
