in my code i used the " texttrgrfrf;" as the type for the email column. i was supposed to use TEXT as the type.but i didn’t. and it’s still working .why?it’s really strange.
here is my code:

CREATE TABLE friends(
id INTEGER,
name TEXT,
birthday DATE
);
INSERT INTO friends(id,name,birthday)
VALUES(1,‘Jane Doe’, ‘1990-05-30’);

INSERT INTO friends(id,name,birthday)
VALUES(2,‘GOOOSFAND’, ‘1990-05-30’);
INSERT INTO friends(id,name,birthday)
VALUES(3,‘KHOROOS’, ‘1990-05-30’);

UPDATE friends
SET name=‘SMITH’
WHERE id=1;

ALTER TABLE friends
ADD COLUMN email texttrgrfrf;

UPDATE friends
SET email= ‘jane@codecademy.com.’
WHERE id=1;

SELECT* FROM friends;

Run SELECT tbl_name, sql from sqlite_master WHERE tbl_name = 'friends'; and post the result.
