Format Unit With Plural

formatUnitWithPlural​

The formatUnitWithPlural function returns a grammatically correct unit string based on the numeric value provided simply by adding s at the end of the unit name. It optionally prefixes the unit with the number.

Pro Tips

  • This function only appends an s at the end of the unit. It does not follow any grammar rules.

  • For complex and versatile pluralization with proper grammar rules, please refer to pluralizer or Pluralizer Class instead.

Function Signature​

formatUnitWithPlural(count: number, unit: string, withNumber?: boolean): string;

Parameters​

  • count: The numeric value used to determine whether the unit should be singular or plural.
  • unit: The base unit string (e.g., "day", "hour", "month").
  • withNumber (optional): Whether to include the number before the unit. Defaults to true.

Return Value​

Returns a properly formatted unit string, such as:

  • "1 day" or "2 days" if withNumber is true.
  • "day" or "days" if withNumber is false.

Example Usage​

With Number​

import { formatUnitWithPlural } from 'nhb-toolbox';

console.log(formatUnitWithPlural(1, 'hour')); // "1 hour"
console.log(formatUnitWithPlural(3, 'day'));  // "3 days"

Without Number​

import { formatUnitWithPlural } from 'nhb-toolbox';

console.log(formatUnitWithPlural(1, 'minute', false)); // "minute"
console.log(formatUnitWithPlural(5, 'month', false));  // "months"

Notes​

  • Automatically pluralizes the unit if the absolute count is not 1.
  • Accepts both positive and negative numbers (e.g., -1 is treated like 1 for pluralization).
  • Does not handle irregular plurals like child -> children instead it does return unit with s. For complex and versatile pluralization, please refer to pluralizer or Pluralizer Class instead.
