如果我们在声明const变量时没有对其进行初始化,那么代码就会抛出一个“'const' declarations must be initialized”的错误。这个错误的意思就是const声明的变量必须要被初始化,不能留下空的值。 让我们来看一个例子: const a; 这段代码会抛出一个“'const' declarations must be initialized”的错误,因为我们没有对...
如果允许const变量不被初始化,那么它就没有任何确定的值,这与常量的定义相违背。 提供如何解决const declarations must be initialized.ts(1155)错误的建议: 要解决这个错误,你需要在声明const变量时立即为其提供一个初始值。例如: typescript const myConstant = 10; // 正确:提供了初始值 而不是: typescript ...
Yes, if someone directs me to how it can be fixed. The text was updated successfully, but these errors were encountered: Owner Ok, I think it is related. The parser we use is TypeScript but a version prior to 4.9 which is the one with the satisfier. It could be this, but it's ...

Storage isn't allocated by "referencing" declarations, nor can variables be initialized in declarations.A storage class or a type (or both) is required in variable declarations. Except for __declspec, only one storage-class specifier is allowed in a declaration and not all storage-class ...
The array must be initialized using a new expression. In addition, all elements in an array initializer must have a best common type. The following examples show how to declare an implicitly typed array:C# Copy var implicitType = new[] { 1, 2, 3 }; char c = 'c'; short s1 = 0...
You can also declareenum,struct, anduniondata types. The syntax is identical to C except thatenummembers can only be initialized to an optionally signed integer constant. scalar_def,declaratorenum_defstruct_defunion_def,declarator ; scalar_def ...
Is of a static data member inside a class declaration. Because static class data members are discrete variables shared by all objects of the class, they must be defined and initialized outside the class declaration. (For more information about classes and class members, seeClasses.) ...
An array element can't be a function type. The second form declares a variable that has been defined elsewhere. It omits the constant-expression argument in brackets, but not the brackets. You can use this form only if you've previously initialized the array, declared it as a parameter, ...
declarations must be initialized at declaration time. This also includes struct variables that have members with bounds. Struct variables can be initialized by declaring a value for the first member of the struct. The remaining values will be initialized to default values, which for pointers is ...
