    Usage

    Requiring the Module

    const findDuplicates = require('@pelevesque/find-duplicates')

    One Set of Duplicates

    const elements = [
      'd131dd02c5e6eec4', // a
      '55ad340609f4b302',
      'd131dd02c5e6eec4', // a
      'd131dd02c5e6eec4', // a
      'd8823e3156348f5b'
    ]
    const result = findDuplicates(elements)
    // result === [[0, 2, 3]]

    Many Sets of Duplicates

    const elements = [
      'd131dd02c5e6eec4', // a
      '55ad340609f4b302',
      'd8823e3156348f5b', // b
      'd131dd02c5e6eec4', // a
      'd8823e3156348f5b', // b
      '551111111114b302', // c
      '551111111114b302'  // c
    ]
    const result = findDuplicates(elements)
    // result === [[0, 3], [2, 4], [5, 6]]

    Using the stopAtFirstSet Flag

    // When using the stopAtFirstSet flag, only the first set is returned.
    // Note: In this case, an array is returned instead of an array of arrays.
    const elements = [
      'd131dd02c5e6eec4', // a
      '55ad340609f4b302',
      'd8823e3156348f5b', // b
      'd131dd02c5e6eec4', // a
      'd8823e3156348f5b', // b
      '551111111114b302', // c
      '551111111114b302'  // c
    ]
    const stopAtFirstSet = true
    const result = findDuplicates(elements, stopAtFirstSet)
    // result === [0, 3]
