const {bar } = foo; // where foo = { bar:10, baz:12 }; /* This creates a constant with the name 'bar', which has a value of 10 */ Set () is a non-const method and constC is a const-qualified object } In the above code, the implicit " this " pointer to Set () has the type " C *const "; whereas the " this " pointer to Get () has type " C const *const ", indicating that the method cannot modify its object through the " this " pointer. the const is after the star symbol, meaning "X* const", and not "const X* or X const*" (which are the same). therefore it means you cannot make "this" point to different object than the one he is pointing at, but you can change the object that is being pointed, which makes sense. "const X* or X const*" means you cannot change the object that is being pointed at the moment, but you can make the pointer point to different objects. hope it helps(: The keyword const is a little misleading. It does NOT define a constant value.

2020-01-03 · const int* const is a constant pointer to constant integer. This means that the variable being declared is a constant pointer pointing to a constant integer. Effectively, this implies that a constant pointer is pointing to a constant value.

// You can create a const object: const car = {type:"Fiat", model:"500", color:"white"}; // You can change a property: car.color = "red"; // You can add a property: car.owner = "Johnson"; the const is after the star symbol, meaning "X* const", and not "const X* or X const*" (which are the same). therefore it means you cannot make "this" point to different object than the one he is pointing at, but you can change the object that is being pointed, which makes sense. "const X* or X const*" means you cannot change the object that is being pointed at the moment, but you can make the pointer point to different objects. hope it helps(: This behavior is somehow different when it comes to objects declared with const.

Feature Request. In the docs, it says that:. Does not support const enums because those require type information to compile.. I don't believe that this is true. Babel should be able to transpile const enums into objects, which will achieve the same functionality as typescript, through different transpiled output.

In this case, the condition is provably false at compile-time, so the user could expand the inline const to contain the if.
