Cannot assign a string value to typescript enum (Initializer type string not assignable to variable type)

Question

You can use an index expression to get the value of the enum:

enum Foo {
    A = "A",
    B = "BB"
}

var foo : Foo = Foo["A"];
var fooB : Foo = Foo["B"];

Note that the key will be the name of the member not the value.

You could also use a type assertion, but you will not get errors if you assign a wrong value:

var foo : Foo = "A"  as Foo;
var foo : Foo = "D"  as Foo; // No error
