Typescript: NumberFormatOptions is missing several options including notation

[benmccann]

notation is missing from NumberFormatOptions

https://github.com/microsoft/TypeScript/blob/91ffa1c752ac26882b1426fb4c9012701c1d908e/lib/lib.es5.d.ts#L4236

TypeScript Version: 3.7.5

Search Terms: NumberFormatOptions notation

Code

const str = new Intl.NumberFormat(undefined, {notation: 'scientific'}).format(100000);

Expected behavior:

I should be able to use NumberFormat's notation option. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat

Actual behavior:

src/core/core.ticks.js(57,43): error TS2345: Argument of type '{ notation: string; minimumFractionDigits: number; maximumFractionDigits: number; }' is not assignable to parameter of type 'NumberFormatOptions'.

Commonly the TypeScript team does not add experimental APIs to the standard library definitions.

You can use Declaration Merging to extend the types yourself. There's probably also a npm package out there that does this for you.

Thanks!

@MartinJohns notation is not experimental anymore. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat/NumberFormat

Can this issue be reopened or I can create a new one if preffered?

@benmccann Any workaround for this for now?

@benmccann Any workaround for this for now?

const shortAmount = new Intl.NumberFormat(undefined, {
  //@ts-ignore
   notation: "compact",
  compactDisplay: "short"
}).format(parseInt(value));

I think the only solution for now is to add a ts-ignore until the types definitions are updated.
