string-char-walker

Library to walk through strings and print or process each character, with unicode support (emojis, accents).

Installation

npm install string-char-walker

Usage

const { printChars, walk } = require('string-char-walker');

// Print a string character by character
printChars('Hello world');
// [0] H
// [1] e
// [2] l
// ...

// Or use walk with your own logic for each character
walk('Hello', (char, index) => {
  console.log(`Character at position ${index}: ${char}`);
});

It also works with ES modules:

import { printChars, walk } from 'string-char-walker';

API

walk(str, callback)

Walks through str and calls callback(char, index) for each character. Uses the native string iterator, so emojis and accented characters are handled correctly. Throws a TypeError if str is not a string.

printChars(str)

Walks through str and prints each character to the console with its index.
