Извлекает символы, начиная с индекса indexA до, но не включая, индекс indexB. \r\n\r\nПример использования:\r\n```js\r\nconst testString = 'Hexlet the best';\r\n\r\nconsole.log(testString.substring(0, 6))\r\n// Вывод:\r\n// -> Hexlet\r\n\r\nconsole.log(testString.substring(7, 10))\r\n// Вывод:\r\n// -> the\r\n\r\n\r\nconsole.log(testString.substring(11))\r\n// Вывод:\r\n// -> best\r\n```\r\n\r\nТак же есть особенности:\r\n- Если аргумент indexA равен аргументу indexB, метод `substring()` вернёт пустую строку.\r\n- Если аргумент indexB опущен, метод `substring()` извлечёт символы начина от indexA до конца строки.\r\n- Если любой из аргументов меньше, либо равен нулю или равен NaN, он будет трактоваться как равный 0.\r\n- Если любой из аргументов больше, чем длина строки, он будет трактоваться как равный длине
