Pattern Matching like a Boss

Regular expressions are like ninja code ninjas - stealthy, efficient, and only visible when they want to be. But have you ever wondered how these regex masters train their skills?

Training RegEx Patterns like a Pro

Start with the basics, like a good samurai starts with a sharp sword. Learn the fundamentals:

• Character Classes: The Building Blocks
• Groups and Captures: The Secret to Success
• Anchors and Quantifiers: The Finishing Moves

Practice your skills with some examples

Let's say you want to match the pattern 'Hello World!' in a string:

const regex = /Hello (\w+)/; const str = 'Hello World!' ; if (str.match(regex)) console.log('Match found!');

Now, try it with some variations:

const regex = /Hello (\w+)/; const str1 = 'Hello World!' ; const str2 = 'Hello, World!'; if (str1.match(regex)) console.log('Match found in str1'); if (str2.match(regex)) console.log('Match found in str2');
