Over my 10+ years of working with Python, I’ve often come across situations where I needed to calculate the absolute value of a number but couldn’t use the built-in abs() function.

After trying a few options, I discovered react-vertical-timeline-component, and it quickly became my go-to choice.

When I started building React applications, I didn’t think much about folder structure. I just created a components folder and dumped everything inside. As the projects grew, I quickly realized this approach made it hard to maintain, scale, and onboard new developers. Searching for a single component felt like digging through a messy closet.
