Transform Your Editor Into a Coding Mentor
Vertex is a next-generation VS Code extension that combines ghost-text guidance, visual call graphs, and AI-powered mentorship to help you master coding character-by-character.
Trace With Code, Master The Logic
function fibonacci(n) {
if (n <= 1) return n;
return fibonacci(n - 1) + fibonacci(n - 2);
}
const result = fibonacci(10);This recursive function breaks down into smaller calls. Notice how fibonacci(n-1) and fibonacci(n-2) create a branching pattern.
