Is there a way to tell the TypeScript compiler to not allow illegal access of private variables via the object map?
For example:
class Thing {
private id: number;
constructor() {
this.id = 1
}
}
var thing = new Thing()
alert(thing["id"]); // I want this to throw a compiler error
There seems to be an inconsistency, although it may turn out to be by design.
In the example below, the compiler determines the type of variable b, but ignores the fact it is private. To be consistent, it should either:
Obviously in your case you are after the second of these options.
class Example {
private private: number;
public public: number;
constructor() {
this.private = 1
}
}
var example = new Example()
var a = example.private; // Error
var b = example["private"]; // number
var c = example["other"]; // any
var d = example["public"]; // number
I have raised an issue for this on GitHub.
