Which in itself depends on is-number (66M weekly downloads).

The beautiful journey seems to end there.

Combining that with https://www.npmjs.com/package/is-string, you can have a JavaScript valid x for which

  isNumber(x) && isString(x)

⇒ isNumber is better named “can-be-used-as-a-number”.

Also, I don’t know JavaScript well enough, but https://www.npmjs.com/package/isnumber is different code from https://www.npmjs.com/package/is-number, but does it have different semantics?

(https://www.npmjs.com/package/lodash.isnumber is different, I think. It (rightfully, IMHO) thinks ∞ and NaN are numbers)

Which used to depend on the legendary `is-is` package. Apparently the maintainer is a certain B. Clinton.

Wow! there are almost 2500 packages on npm that depends on is-number. That's insane.
