Why Automation Breaks Most automation scripts fail for predictable reasons. Once you understand these failure modes, you can design around them. Here are the six most common causes of broken automation. 1. API Changes This is the most common problem. You build a script that depends on an API response structure: { “users”: […] } Six months later the API changes to: { “data”: […] } Your script crashes — or worse, processes incorrect data.

When building an Express.js server, you may encounter some unexpected behaviors while handling routes, especially when using app.use(). I was watching the “Creating Our Express Server” episode from the _Namaste Node.js_ course. While experimenting with app.use(), I stumbled upon an intriguing behavior related to middleware and routing order. This prompted me to dig deeper into how app.use() works and compare it with app.get(). Here’s a detailed look into these behaviors, why they occur, and how to address them: I wrote the following code: _const_ blog = await CommonService.getData( CONSTANTS.BLOG_COLLECTION, “slug”, slug, [“_id”, “title”, “description”, “categories”, “tags”, “slug”, “status”, “createdAt”] ); When I navigated to http://localhost:3000, I correctly…

🔷 Imagine a child observing their grandparent’s special style of walking. Even after the grandparent leaves, the child remembers and mimics that exact walk, step by step. In JavaScript, closures work similarly.🔷 A closure is a function that remembers the environment it was created in.🔷 Just like the child remembers their grandparent’s walk, closures “remember” variables from their outer function—even after the outer function has finished executing.💎 Why are closures important?⏩ Closures allow functions to “remember” the environment where they were created.🔷 This makes them incredibly useful for :1️⃣ Data privacy : You can create private variables that can’t be accessed directly.2️⃣ Maintaining state : Closures help retain values across…
