I'm currently scraping some files from a website manually, by finding a certain .js file in the Source tab in devtools, add breakpoint to a specific line of code, then run javascript code in the Console when it stops at that breakpoint. I also click continue breakpoint button and run another javascript code. My question is, how can i programmatically do this using Puppeteer? i know how to evaluate code in a website but don't know how to add breakpoint to website's own .js file inside the source.
