😵 "Complexity kills."
This is especially true in software development.
Have you ever tried to add a new feature and it took weeks instead of days, causing new bugs?
😱 Let's explore coupling and how it can affect your system!
- A THREAD -
📝 Example:
function displayData() {
const rawData = "hello";
console.log(formatData(rawData));
}
function formatData(data: string): string {
return data.toUpperCase();
}
`displayData` depends on `formatData`. If `formatData` changes, `displayData` must change too.
How can we solve the coupling?
🔄 Reduce coupling by passing dependencies as parameters:
function displayData(formatter: (data: string) => string) {
const rawData = "hello";
console.log(formatter(rawData));
}
Now, `displayData` is more flexible and less dependent on `formatData`.
🚀 Why is this better?
The refactored version allows `displayData` to work with any function that formats data. This makes it easier to change or extend functionality without modifying `displayData`.
🧐 This is just a tiny example, but there's a lot more to reveal about coupling and its impact on software design.
