Code Examples

import { digitToBangla } from 'bn-calendar/utils';

// 1. Default Behavior (preserveNonDigit = true)
console.log(digitToBangla(123));                  // "১২৩"
console.log(digitToBangla(4567));                 // "৪৫৬৭"
console.log(digitToBangla('123'));                // "১২৩"
console.log(digitToBangla('12ab34'));             // "১২ab৩৪"
console.log(digitToBangla('abc'));                // "abc"
console.log(digitToBangla(''));                   // ""

// 2. Stripping non-digits (preserveNonDigit = false)
console.log(digitToBangla('12ab34', false));      // "১২৩৪"
console.log(digitToBangla('abc', false));         // ""
console.log(digitToBangla('১২৩', false));         // "১২৩"
console.log(digitToBangla('', false));            // ""

// 3. Real-world strings
console.log(digitToBangla('Phone: 01712345678')); // "Phone: ০১৭১২৩৪৫৬৭৮"
console.log(digitToBangla('আমার বয়স 25 বছর'));        // "আমার বয়স ২৫ বছর"
