| /** | |
| * This gist demonstrates how powerful TypeScript's new tuple type is. | |
| * Say, we want to write a function that receive multiple arguments, and return a tuple of arguments' types. | |
| * For example, `getTypes(1, true, 'str')` return a tuple `['number', 'boolean', 'string']`. | |
| * We can do that in **type safe** way in TypeScript now! And actually we can do the computation at compile time! | |
| * This is so like dependent type in TypeScript! | |
| * Reference: https://github.com/Microsoft/TypeScript/pull/24897 | |
