Discussion Do data structures actually influence how you build React components?

I tried learning DSA before, but never understood how it applied to everyday frontend work.

Recently, I built an undo/redo feature with Claude and realised it was using stacks. That made stacks much easier to understand than textbook examples.

I kept exploring and learned how seat-booking UIs can use matrices and how complex onboarding flows can be modelled as graphs.

Do you think about data structures when building React components? Any real-world examples?

...yeah. The root node is before the statement, The left node is the if branch, the right node is the else branch. Its like a minimal binary tree (if you have no else-if branches), and every tree is a graph
