Partition strings based on character indices.

Install

yarn add strind

Usage

import strind from 'strind';

const result = strind('abcd', [[1, 1], [2, 6]]);

console.log(result);
/**
 * {
      matched: ['b', 'cd'],
      unmatched: [
        {
          chars: 'a',
          index: 0
        }
      ]
    }
 *
 */

Callback

An optional callback function can be passed as the third argument.

The function is called with the substring chars and boolean matches if the substring matches the array indices.

import strind from 'strind';

const result = strind('abcd', [[1, 1], [2, 6]], ({ chars, matches }) => {
  return {
    text: chars,
    isHighlighted: matches
  };
});

console.log(result);
/**
 * [
      { isHighlighted: false, text: 'a' },
      { isHighlighted: true, text: 'b' },
      { isHighlighted: true, text: 'cd' }
    ]
 *
