Those are unfortunately not the same. The second one (with an explicit radix of 10) is correct; the first is not (or is at least a bit riskier). See https://dev

In most browser implementations (at least all the ones we develop for) it would assume a radix of 10 for those values specifically.

But see also https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt#Octal_interpretations_with_no_radix https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... and especially https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt#Browser_compatibility https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... — that comment is increasingly stale unless you support browsers which are no longer supported by their vendors like IE8.

  Good point. I've edited my comment to be more qualified.

    The web is a fascinating study of advice that changed over time: there’s something like a half-decade window where the two argument form became common, with unsafe usage before and safe usage after.

this is a relic from issues in ie8, and you no longer need to do this if you're not supporting ie8. hell even if you use ie8 in almost 99% of cases you won't need to bother.
