This is just for the sake of completeness - it is not relevant in the given example. This is the behaviour that leads to the temporal dead zone. * const declarations are hoisted in JavaScript. Thus only getCarDetails() will be hoisted when the code runs. This TypeScript code does not use hoisting*: const x: Foo = ) This JavaScript code works due to hoisting: fn() To be clear with terminology - 'hoisting' refers to declarations being processed before running the code. Is it safe to assume it happens due to hoisting as a part of transpilation or else there is something else involved here.

The code transpiles fine even though I declared interface after the function that is using it. It would exhibit the same behaviour whether or not TypeScript is there. However, if the question is ' Does code written in TypeScript still exhibit hoisting behaviour?', the answer is ' Yes, it does, but not in any way related to the fact that it is written in TypeScript'. Prior to trialing the standing hoist with the client, I asked one carer to trial it on the second carer first, as I usually do during face-to-face visits.

Which is (potentially) far after the TypeScript compiler has finished with it. It is the JavaScript engine that does it when it executes the code. That is to say, it has no influence over hoisting. TypeScript has as much of an impact on that as Notepad++ - whether you actually write your code there or not. While 'hoisting' is a concept related to running JavaScript code.

TypeScript does not exist at runtime, only at compile time. If your question is ' Does TypeScript cause hoisting behaviour of the code?' then the answer is ' No, it does not'.
