What are the advantages and disadvantages of using the ORM library TypeORM in a project?

Advantages of TypeORM:

• Allows working with the database through objects and classes, which simplifies code and improves readability.
• Supports many DBMS (PostgreSQL, MySQL, SQLite, etc.), providing flexibility.
• Automatic creation and migration of database schema.
• Integration with TypeScript, ensuring typing and autocompletion.

Disadvantages:

• May reduce performance compared to pure SQL queries due to an additional layer of abstraction.
• Sometimes complex queries are hard to express through ORM, leading to the need to write "raw" SQL.
• Steep learning curve for beginners due to numerous features and configurations.
• Scalability issues may arise in very large projects and complex schemas.

Overall, TypeORM is convenient for quick startups and medium-sized projects, but for high-load systems, more fine-tuning or native queries may be required.
