Ask HN: Need Help Understanding Pine Script for JavaScript Conversion

I have a Pine Script for a TradingView indicator, but I need to understand the strategy behind it before converting it into JavaScript code that can process an array of price actions for signals. Reading Pine Script is challenging for me, and I find it difficult to translate it into JavaScript. Can anyone assist me with this?
