TypeScript confusion

type First<T> = T extends any[] ? T[0] : never;

const myarr = [1, 2, 3]

type FirstItem = First<myarr>; // This errors saying you should pass type instead of value

type FirstItem1 = First<[1, 2, 3]> // This works even if we are passing value

type First<T> = T extends any[] ? T[0] : never;

const myarr = [1, 2, 3]

type FirstItem = First<myarr>; // This errors saying you should pass type instead of value

type FirstItem1 = First<[1, 2, 3]> // This works even if we are passing value
