Day 19: Regular Expressions

Tasks/Activities:

Activity 1: Basic Regular Expressions

• Task 1: Write a regular expression to match a simple pattern (e.g., match all occurrences of the word "JavaScript" in a string). Log the matches.
• Task 2: Write a regular expression to match all digits in a string. Log the matches.

Activity 2: Character Classes and Quantifiers

• Task 3: Write a regular expression to match all words in a string that start with a capital letter. Log the matches.
• Task 4: Write a regular expression to match all sequences of one or more digits in a string. Log the matches.

Activity 3: Grouping and Capturing

• Task 5: Write a regular expression to capture the area code, central office code, and line number from a US phone number format (e.g., (123) 456-7890). Log the captures.
• Task 6: Write a regular expression to capture the username and domain from an email address. Log the captures.

Activity 4: Assertions and Boundaries

• Task 7: Write a regular expression to match a word only if it is at the beginning of a string. Log the matches.
• Task 8: Write a regular expression to match a word only if it is at the end of a string. Log the matches.

Activity 5: Practical Applications

• Task 9: Write a regular expression to validate a simple password (must include at least one uppercase letter, one lowercase letter, one digit, and one special character). Log whether the password is valid.
• Task 10: Write a regular expression to validate a URL. Log whether the URL is valid.

Feature Request:

1. Basic Regex Script: Write a script that uses regular expressions to match simple patterns and log the matches.
2. Character Classes and Quantifiers Script: Create a script that uses regular expressions to match words with specific characteristics and log the matches.
3. Grouping and Capturing Script: Write a script that uses regular expressions to capture parts of a string, such as phone numbers and email addresses, and log the captures.
4. Assertions and Boundaries Script: Create a script that uses regular expressions to match words at specific positions in a string and log the matches.
5. Validation Script: Write a script that uses regular expressions to validate passwords and URLs and log whether they are valid.

Achievement:

By the end of these activities, students will:

• Understand and create basic regular expressions.
• Use character classes and quantifiers in regular expressions.
• Implement grouping and capturing in regular expressions.
• Apply assertions and boundaries in regular expressions.
• Use regular expressions for practical applications like validating passwords and URLs.
