TypeScript class with private fields not being accessed correctly in nested functions

typescript class private TypeScript

I've been banging my head against this for hours. I've searched everywhere and can't find a clear answer. I've been struggling with this for a few days now and could really use some help... I'm working with an scenario with accessing private fields in a TypeScript class when using nested functions. I have a class that looks something like this: ```typescript class MyClass { private myValue: number; constructor(value: number) { this.myValue = value; } public someMethod() { const nestedFunction = () => { console.log(this.myValue); // This should log the private field }; nestedFunction(); } } const instance = new MyClass(42); instance.someMethod(); ``` When I run this code, I expect to see `42` printed in the console. However, I get the following behavior instead: ``` Property 'myValue' is private and only accessible within class 'MyClass'. ``` I have tried changing the access modifier of `myValue` to `public`, and it works as expected, but I really want to keep it private for encapsulation reasons. I also checked that I am not trying to access it from outside of the class. Is there something I'm missing about how TypeScript handles private fields in nested functions? Is it a limitation of TypeScript or am I using the syntax incorrectly? Any insights would be greatly appreciated! What's the best practice here? I'm working with Typescript in a Docker container on Debian. What would be the recommended way to handle this?
