Hi,

Let's say you're building a photo editing app that allows users to add filters and effects to their photos. The app loads the original photo into memory and then applies the selected filters and effects to it. However, you haven't optimized the memory usage in your app, and you're using a lot of memory to store the edited photo. Now imagine a user with an older device or a device with limited RAM tries to use your app. The device doesn't have enough available memory to store the edited photo, and the app crashes with an OOM error. To prevent this scenario, you need to optimize the memory usage in your app. For example, instead of loading the entire photo into memory, you can load it in chunks and process each chunk separately. You can also compress the edited photo before storing it in memory. Additionally, you can use memory profiling tools to identify any memory leaks or inefficient memory usage patterns in your app.

I hope this helps!

I will add this answer to article, too.

Happy coding 🎉
