Snowflake - Build and Architect Data Pipelines Using AWS - Lab - Implement JavaScript UDFs

The video tutorial introduces writing User Defined Functions (UDFs) in JavaScript, starting with a scalar function that converts a string to a date. It then explains a tabular function that generates a range of IP addresses. The tutorial highlights the use of JavaScript UDFs for simple operations and contrasts them with SQL UDFs. The video concludes with a brief mention of upcoming topics like secure UDFs and pushdown.
