 ## Tagged template function ``` sql`` ``` 
 [Tagged template functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#Tagged_templates) are not just ordinary template literal strings. They allow the function to handle any parameters within before interpolation. This means that they can be used to enforce a safe way of writing queries, which is what Postgres.js does. Any generic value will be serialized according to an inferred type, and replaced by a PostgreSQL protocol placeholders `$1, $2, ...` and then sent to the database as a parameter to let it handle any need for escaping / casting.
 
-This also means you cannot write dynamic queryes or concat queries together by simple string manipulation. To enable dynamic queries in a safe way, the `sql` function doubles as a regular function which escapes any value properly. It also includes overloads for common cases of inserting, selecting, updating and querying.
