Usage

JavaScript

Once installed, you can import and use the function in your JavaScript project like this:

const isFifteen = require('is-it-fifteen')

console.log(isFifteen(15)) // true
console.log(isFifteen(10)) // false
console.log(isFifteen(25)) // false

TypeScript

If you are using TypeScript, the package comes with built-in TypeScript type definitions, so you get full type support out of the box.

import isFifteen from 'is-it-fifteen'

console.log(isFifteen(15)) // true
console.log(isFifteen(10)) // false
console.log(isFifteen(100)) // false

API

isFifteen(number: number): boolean

• number (number): The number to check.
• Returns: A boolean value (true if the number is 15, false otherwise).

Example:

console.log(isFifteen(15)) // true
console.log(isFifteen(20)) // false
console.log(isFifteen(-15)) // false

TypeScript Support

This package fully supports TypeScript, providing type definitions (.d.ts) for better development experience. You can use it directly in your TypeScript projects without needing to install additional type packages.

Example TypeScript Declaration:
