I am learning JavaScript and am working my way through [this](https://www.learn-js.org/en/Arrays) tutorial. I am wondering if this statement is, in fact, correct: >Arrays in JavaScript are sparse. The following code produces `5`, instead of `1` as I would have expected, if the array was really sparse: ``` const a = [1]; a[5] = 1; a.pop(); console.log(a.length); ``` [jsfiddle](https://jsfiddle.net/wfuhpsk0/)
