Node JS not compiling my private instance variable-CodePudding

Right now I have a class that is similar to below

class Rectangle {
    #height = 0;
    #width;
    constructor(height, width) {
      this.#height = height;
      this.#width = width;
    }
}

If i tried to compile this with node.js, it gives me the following error.

    #height = 0;
    ^

SyntaxError: Invalid or unexpected token

    at startup (internal/bootstrap/node.js:283:19)
    at bootstrapNodeJSCore (internal/bootstrap/node.js:623:3)

Does anyone know how to resolve this?

I tried making the variable public and also static, but nothing prevents it from throwing the error above.

Your issue derives most likely from an outdated version of node.js, ensure you have the latest version downloaded.
