What is the output of the following? “`js class Counter { #count = 0; increment() { this.#count++; } get value() { return this.#count; } } const c = new Counter(); c.increment(); c.increment(); console.log(c.value); console.log(c.#count); “`

Accepted Answer

The output will be 2 then SyntaxError. The value of the counter is correctly accessed using `c.value`, but trying to access the private field `#count` directly will result in a SyntaxError.
