Javascript methods have JS api and one API that created memory leaks or at least is under the radar is setTimeout, read the full story to get the context in detail but the overview is simple, even after clearing the setTimeout interval or method it still stores the reference in the browser causing the memory leakage. Of course, we can't be sure blaming only one JS browser API but this can be the one big adding factor.

Web Scraping Business Idea for Devs

Web scraping is always and still is a task and data science projects as well as data training for AI models need web scraping as the first step for data collection.

Last week I shared an open-source web scraping package earning tonnes of $$$ so this also sounds like a good small project for a lot of developers. 

Following ways to monetise your web scraping project

• Open-source the API for subscription 
• Sell API on Rapid API and other similar platforms
• Sell exclusive and cleaned data on Kaggle and other similar platforms
• Sell Notion templates, Airtable, and Google sheet as the dataset

For reference, look at the Rapid API Web Scraping APIs

DSPy - Alternative to Prompt Engineering in Programming

Remember the hype of Prompt Engineering, well it is still the most in-demand skill.
