+ * @name lightFormat
+ * @category Common Helpers
+ * @summary Format the date.
+ *
+ * @description
+ * Return the formatted date string in the given format. Unlike `format`,
+ * `lightFormat` doesn't use locales and outputs date using the most popular tokens.
+ *
+ * > ⚠️ Please note that the `lightFormat` tokens differ from Moment.js and other libraries.
+ * > See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
+ *
+ * The characters wrapped between two single quotes characters (') are escaped.
+ * Two single quotes in a row, whether inside or outside a quoted sequence, represent a 'real' single quote.
+ *
+ * Format of the string is based on Unicode Technical Standard #35:
+ * https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
+ *
+ * Accepted patterns:
