Application Security Languages

Here's a rough list:

• Angular
• C/C++
• C# .NET
• Go
• Java
• Java Spring
• JavaScript
• Kotlin
• Node.js
• PHP
• Python
• Rails
• TypeScript
• Vue.js

Hope that helps!

As BarnyStewart pointed out we've got 14 languages (and counting) on offer. I'll expand a little on the frameworks you can expect to see when attempting some of the secure coding practical labs. 

• Node.js
  • Front End - React
  • Back End - Express.js
• TypeScript
  • Back End - Nest.js
• Python
  • Front End - Jinja Templating
  • Back End
    • API labs - Fast API
    • Beginner/Inter/Advanced - Flask
• Go
  • Back End - Echo

Hope that gives you a little more info into some of the stacks you can expect to see. We're typically aiming to use industry and enterprise tested stacks so we can have our secure coding concepts be the main focus while keeping it realistic.
