How to enter debug mode

There are two ways to launch the debugger.

Launching a command

Let's suppose that we have to debug the following method

In the business world, every second counts, and having high-performing applications is essential for streamlining our business processes. We understand the significance of crafting efficient algorithms, measurable through the big O notation.

We are back to %SYS once again! Since we covered managing users and resources in the last two articles, we can finally move on to roles. As you may have guessed, there are a lot of methods of managing them that you have already seen in our previous writings.

Introduction

Visual Studio Code (VS Code) is a free source code editor made by Microsoft for Windows, Linux, and macOS. It provides built-in support for JavaScript, TypeScript, and Node.js. You can add extensions to provide support for numerous other languages including ObjectScript.

The InterSystems extensions enable you to use VS Code to connect to an InterSystems IRIS server and develop code in ObjectScript. The Visual Studio Code Documentation is an excellent resource on VS Code, so it is a good idea to be familiar with it.
