Guide to accessing private property in TypeScript using the prefix # syntax

Is there a way to access private properties of a class in TypeScript that are denoted by the prefix # symbol? I need this for unit testing purposes.

class A {
    #pr: number;
    pu: number
    constructor(pr: number, pu: number) {
        this.#pr = pr;
        this.pu = pu;
    }
}

let a = new A(10, 9);

console.log(a.pu, a.#pr);

I attempted using console.log(a.pu, a["#pr"]); but it did not work. Any suggestions?

Answer №1

Currently, it is impossible to access or identify the utilization of (non-polyfilled) private fields, rendering them effectively "hard-private."
