+ * Truncates `string` if it's longer than the given maximum string length.
+ * The last characters of the truncated string are replaced with the omission
+ * string which defaults to "...".
+ *
+ * @param [string=''] The string to truncate.
+ * @param [options={}] The options object.
+ * @param [options.length=30] The maximum string length.
+ * @param [options.omission='...'] The string to indicate text is omitted.
+ * @param [options.separator] The separator pattern to truncate to.
+ *
+ * @example
+ * const test = 'hi-diddly-ho there, neighborino';
+ * const truncatedStr1 = truncate(test) // returns 'hi-diddly-ho there, neighbo...'
+ * const truncatedStr2 = truncate(test, { length: 24, separator: ' ' }) // returns 'hi-diddly-ho there,...'
+ * const truncatedStr3 = truncate(test, { length: 24, separator: /,? +/ }) // returns 'hi-diddly-ho there...'
+ * const truncatedStr4 = truncate(test, { omission: ' [...]' }) // returns 'hi-diddly-ho there, neig [...]'
+ * const truncatedStr5 = truncate('ABC', { length: 3 }) // returns 'ABC'
+ * const truncatedStr6 = truncate('ABC', { length: 2 }) // returns '...'
+ * const truncatedStr7 = truncate('¥§✈✉🤓', { length: 5 }) // returns '¥§✈✉🤓'
+ * const truncatedStr8 = truncate('¥§✈✉🤓', { length: 4, omission: '…' }) // returns '¥§✈…'
