In this video, I share a valuable lesson I learned by making a mistake during my early days as a software developer. Join me as I recount my experience working on a task involving querying the battery levels of thousands of devices using an API call. With enthusiasm, I wrote a Node.js script that processed each device one by one, making hundreds of API requests per second. However, my script kept failing, leading to frustration and confusion. It was through this experience that I discovered the critical concept of throttling or rate limiting.

I explain why rate limiting is vital in software development, as it prevents users from overwhelming servers with an excessive number of requests. I discuss how failing to implement rate limiting can not only slow down your server but also make it vulnerable to attacks and incur significant costs, especially when relying on external services like databases or APIs. By embracing rate limiting, we protect our servers and optimize resource utilization. Join me as I delve into the importance of rate limiting and share my personal journey of learning this crucial concept.
