Formatting Values With Units For Display

There are all kinds of values and units your app may need to display. The Intl.NumberFormat API that is available in modern browsers can help with standardizing that display.

How about formatting distances for display?

Here is a compact formatting of miles:

> const milesFormat =
    Intl.NumberFormat("en-US", { style: "unit", unit: "mile" });
> milesFormat.format(1500)
"1,500 mi"

Here is two different formats for kilometers:

> const kmFormat =
    Intl.NumberFormat("en-US", { style: "unit", unit: "kilometer" });
> kmFormat.format(1500)
"1,500 km"
> const kilometerFormat =
    Intl.NumberFormat("en-US", { style: "unit", unit: "kilometer", unitDisplay: "long" })
> kilometerFormat.format(1500)
"1,500 kilometers"

Give it a try with something else like miles-per-hour, liter, or gallon.
