It's not a failure of the language. Javascript has comparison operators like every other language, it's entirely possible to determine if a number is greater than or less than zero without importing a third-party package.
What it is is a failure of modern JS development culture, because apparently it's anathema to even write a simple expression on your own rather than import a dependency tree of arbitrary depth and complexity and call a function that does the same thing.
