This article demystifies literals, exploring what it is, what types exist, and how to use them, offering a few examples, and addressing the most asked questions.

aliases, and you cannot use type aliases to create different versions of the same type. When you use a type alias, it is the same as the type you wrote. In other words, the code may look illegal, but it is still legal for TypeScript, because both types are aliases of the same ...
String literals are enclosed in double quotes and may not extends past the end of a line. Technically string literals (but not values) are allowed to have a length of up to 1023 characters. Internally strings are zero-terminated, which means no string can contain the null character because ...
