Nodejs - RangeError: Value unit out of range for numberformat options property style

Question

I am trying to use NumberFormat in NodeJS. It is working perfect for style "currency" but for style "unit" it is throwing the error: RangeError: Value unit out of range for numberformat options property style

Here is my code:

Intl.NumberFormat("en-US", {
    style: "unit",
    unit: "kilometer-per-hour",
  }).format(71);

This is only happening in NodeJS. I tried the same code in browser console and it worked perfectly.

languages are supported.. but the style "unit" is giving problem. Other styles like "currency", "decimal" are working fine. — Sid, May 12 '21 at 07:46

You need to use polyfill to support in all browser.

const formatter = new Intl.NumberFormat('en', {
  style: 'unit',
  unit: 'kilometer-per-hour',
});

console.log(formatter.format(7024));
