Debugging React can sometimes feel like chasing shadows. I still remember one of my first React projects where I was stuck for hours because a simple component refused to render. No error messages, no warnings, just a blank screen. Over the years, I’ve run into this issue multiple times, both in personal projects and while … Read more >>
Building React applications over a decade ago, one of the most common requests from clients was to add a search feature. It sounds simple, but a search bar can drastically improve the user experience. Whether you’re building an e-commerce site, a blog, or a data-heavy dashboard, users need a quick way to find what they’re … Read more >>
While working on large-scale React applications, I quickly noticed performance issues caused by unnecessary re-renders. That’s when I leaned on Pure Components to optimize my code and keep the UI snappy. In this tutorial, I’ll walk you through what Pure Components are, how they work, and how you can use them in your own React … Read more >>
When I first started working with React, one of the challenges I faced was figuring out how to trigger a function in a child component directly from the parent.

Recently, I was working on a React project where I needed to test a dashboard component.The dashboard relied on several child components, and I wanted to isolate the parent logic without worrying about the child implementations. The issue is… when you render the full component tree in tests, it often makes debugging harder. So, mocking … Read more >>
While working on a React project, I ran into a warning that said: At first, it looked harmless, but I quickly realized it could lead to memory leaks and unpredictable behavior in my app. Since I’ve spent more than a decade writing Python and JavaScript code, I’ve learned that these small warnings often point to … Read more >>
As a developer, I was working on a Python project where I had to create multiple charts in one figure. The problem was that the default subplot sizes in Matplotlib were too small, and the labels were overlapping. As someone who has been coding in Python, I’ve faced this issue countless times. Thankfully, Matplotlib gives … Read more >>
