Named capturing groups in JavaScript regex?

📝 Blog Post: Named Capturing Groups in JavaScript Regex? 🧩

👋 Hey there tech enthusiasts! Welcome to my tech blog! Today, let's dive into the intriguing world of named capturing groups in JavaScript regex. 🎉

🤔 Question: "As far as I know there is no such thing as named capturing groups in JavaScript. What is the alternative way to get similar functionality?". 💭

💡 Problem: So, you want to use named capturing groups in JavaScript regex, huh? Well, brace yourself because JavaScript doesn't have built-in support for this feature. 😱 But don't worry, there's always a way around it!

✅ Solution: Here's a neat alternative approach to achieve similar functionality:

1️⃣ Using numbered capturing groups: Instead of using names to refer to capturing groups, we can rely on their positional order in the regex pattern. For example, if we want to capture a specific part of a string, we can do it like this:

const regex = /(hello) (world)/;
const match = regex.exec('Say hello world!');
console.log(match[1]); // Output: hello
console.log(match[2]); // Output: world

In this example, (hello) and (world) act as capturing groups, and we can access their values using match[1] and match[2], respectively.

2️⃣ Leveraging object destructuring: With the help of object destructuring, we can assign meaningful names to captured groups during pattern matching. Take a look at this code snippet:

const regex = /(?<greeting>hello) (?<name>world)/;
const match = regex.exec('Say hello world!');
const { groups: { greeting, name } } = match;
console.log(greeting); // Output: hello
console.log(name); // Output: world

By using (?<greeting>hello) and (?<name>world) as named capturing groups, we can now access their values using greeting and name respectively instead of numeric indices.

📢 Call to Action: So, there you have it, fellow techies! Remember, even though JavaScript doesn't provide built-in support for named capturing groups, we have clever workarounds! 😎
