In TypeScript, which primitive type is implicitly used for variables that are assigned `null` or `undefined` when strict null checks are disabled?
Consider the following TypeScript code: `let value: number | string = 10; value = "hello";`. If `value` were declared with `const` instead of `let` (`const value: number | string = 10;`), what would be the consequence if you attempted `value = "hello";`?
In TypeScript, what is the primary distinction between the `symbol` primitive type and a regular string literal when used as property keys?
