    This PHP function performs a regex search and replace using a callback.

    Code:
    preg_replace_callback(
        string|array $pattern,
        callable $callback,
        string|array $subject,
        int $limit = -1,
        int &$count = null,
        int $flags = 0
    ): string|array|null

    JavaScript arrow functions are terse and great for callbacks.

    JavaScript:
    const materials = [
      'Hydrogen',
      'Helium',
      'Lithium',
      'Beryllium'
    ];
    
    console.log(materials.map(material => material.length));
    // expected output: Array [8, 6, 7, 9]
