Generally the understanding happens fairly quickly just by glancing through the code.

I was a sceptic up until recently, where I failed to create a solution myself.

Since I am mostly a hobbyist programmer(for 25 years and counting) I often find I don’t have the time to sit down for prolonged periods to reason about my code.

ChatGPT helps my tired brain from work develop my code 10x quicker, easily, by removing road blocks for me.

I find it an excellent tool.
