Snowflake allows users to write custom application logic in JavaScript for two types of objects: Stored Procedures and User-Defined Functions (UDFs).

Stored Procedures:Snowflake stored procedures can be written in JavaScript to encapsulate complex business logic and procedural operations.

CREATE OR REPLACE PROCEDURE my_procedure()

RETURNS STRING

LANGUAGE JAVASCRIPT

EXECUTE AS CALLER

AS

$$

// JavaScript logic here

$$;

User-Defined Functions (UDFs):Snowflake UDFs can be written in JavaScript to perform custom calculations or operations on data.

CREATE OR REPLACE FUNCTION my_function(x FLOAT)

RETURNS FLOAT

LANGUAGE JAVASCRIPT

AS

$$

return x * 2;

$$;
