It does not mean the value it holds is immutable-just that the variable identifier cannot be reassigned. The const declaration creates a read-only reference to a value. (This makes sense, given that it can't be changed later.) You must specify its value in the same declaration. Global constants do not become properties of the globalThis object, unlike var variables.Īn initializer for a constant is required. This declaration creates a constant whose scope can be either global or local to the block in which it is declared.
