When working with Typescript, I've noticed that my code is sometimes accepted by the compiler even when I mistakenly write name instead of someObject.name.
To test this behavior, I compiled a file with just console.log(name) and surprisingly, the Typescript compiler accepted it. Could there be some global symbols defined in Typescript?
My current setup includes Typescript 2.8.1 and only NPM itself along with Typescript as global packages.
A specific library exists for the EcmaScript standard, known as ES2016. This library is referred to as "lib.es2016.full.d.ts" (https://github.com/Microsoft/TypeScript/blob/master/lib/lib.es2016.full.d.ts) and it includes the declaration for the "name" property.
In certain code editors (such as Visual Studio Code), you can access the definition of "name" by selecting "Go to definition" from the context menu. Alternatively, you can hover over "name" to see its type (which is "never" and const).
This was implemented to restrict access to the global (Window) name property: https://github.com/Microsoft/TypeScript/issues/1351 https://github.com/Microsoft/TypeScript/issues/9850
