These should be throw new Error, not throw Error. Invoking constructors without the new keyword is deprecated.

I can't find a reference supporting this. I used to write new Error but stopped because it's extra tokens for seemingly no value. The ES5 spec specifically permits this. Is there an ES6 reference that says otherwise?
I only bring it up because I'd enforce what you're asking for if I had a good reference.

Ah, interesting @paulmelnikow! That's still in the ES2015 spec (https://www.ecma-international.org/ecma-262/6.0/#sec-error-constructor):
When Error is called as a function rather than as a constructor, it creates and initializes a new Error object. Thus the function call Error(…) is equivalent to the object creation expression new Error(…) with the same arguments.
I guess it's okay then. I was basing my info off an internal lint rule we have at Facebook, but perhaps the info is outdated/incorrect.

Do
module.exports = {
age,
colorScale,
};
for consistency with the other modules you've created?

I'd suggest to put this require call inside the formatDate method so you only incur the overhead of loading moment if it's really needed.

When would avoiding that overhead be helpful?

What's the purpose of Number.EPSILON here?
There was a problem hiding this comment.
The semantics of colorScale are that the color shifts into the new color when the value >= the provided step value. By making this EPSILON, a value of 0.5 produces yellow. If it were 1 it would be red.

Can you just use 0, or do you want to differentiate 0 from "any possible value after 0"?
There was a problem hiding this comment.
The existing percentage function makes 0 red and anything after that yellow. I don't see the point in differentiating between 0 and 1, which both seem terrible, though I was aiming for parity.

I added tests at 0.5 to clarify this.
