Oracle Database supports a rich set of languages for writing user-defined functions and stored procedures, including PL/SQL, Java, and C. With Oracle Database Multilingual Engine (MLE), developers have the option to run JavaScript code through dynamic execution or with persistent MLE modules stored directly in the database.

The landscape of programming languages is rapidly evolving, with more developers choosing to use modern dynamic languages like JavaScript. Besides simpler syntax and support for modern language features, a key factor in the popularity of these languages is the existence of a rich module ecosystem. Developers often choose to use different languages to implement different parts of a project, based on the availability of suitable modules for the given task.

Whether or not a new language reaches widespread adoption frequently depends on community involvement. Once a language reaches some threshold of popularity, its ecosystem often starts expanding rapidly, attracting more and more developers. Many times, a rich set of features, libraries, and reusable code modules are created to support more widespread use.

The Oracle Database is renowned for its support of a rich ecosystem of programming languages. The most common programmatic server-side interface to the Oracle Database is PL/SQL. By using PL/SQL it is possible to keep business logic and data together, oftentimes offering significant improvements to efficiency in addition to providing a unified processing pattern for data, regardless of the client interface in use. With MLE, you can utilize PL/SQL to implement JavaScript modules, offering an additional avenue to interact directly with the database.

• The Need for a Multilingual Engine
  The benefits of using MLE to process data within the database are described.
• Overview of JavaScript
  One of the most popular programming languages today, JavaScript runs on any machine with a JavaScript engine. Developers prefer JavaScript mainly for the ease of scripting to develop end-to-end applications and for fast execution.
• Overview of Multilingual Engine for JavaScript
  MLE allows you to run and store JavaScript directly in the Oracle Database.
• Introduction to Debugging JavaScript Code
  MLE allows you to debug your JavaScript code by conveniently and efficiently collecting runtime state during program execution.
