Check this code
interface PriceFormatOptions {
unit: string;
}
export default class PriceHelper {
/**
* Adds unit and separates thousands
*/
static format(
price: Parameters<typeof PriceHelper.#separateThousands>[0],
options: PriceFormatOptions = {} as PriceFormatOptions
) {
let unit = options.unit || "تومان";
const separatedPrice = this.#separateThousands(price);
if (unit) unit = ` ${unit}`;
return separatedPrice + unit;
}
/**
* Converts numeral prices to persian words
*/
static toWords() {}
static #separateThousands(price: string | number) {
return String(price || 0).replace(/B(?=(d{3})+(?!d))/g, ",");
}
}when I wite separateThousands like this
static separateThousands(price: string | number) {
return String(price || 0).replace(/B(?=(d{3})+(?!d))/g, ",");
}
and use it like this
price: Parameters<typeof PriceHelper.#separateThousands>[0],
everything is fine but when I use it as private field (with #) like above code snippet typescript complains with this error
ESLint: Parsing error: Identifier expected.
on this line
price: Parameters<typeof PriceHelper.#separateThousands>[0],
I don’t have any idea how can I fix that
