TypeScript Types All In One

any, void, unknown, never,

interface, decorator, <T>范型, class, Tuple 元组

/*

There are already a small set of primitive types available in JavaScript:
boolean, bigint, null, number, string, symbol, and undefined,
which you can use in an interface.

TypeScript extends this list with a few more, such as
any (allow anything),
unknown (ensure someone using this type declares what the type is),
never (it’s not possible that this type could happen), and
void (a function which returns undefined or has no return value).

// JS: boolean, bigint, null, number, string, symbol, and undefined,

// TS: any, unknown, never, void
