Visualizing `String` and `RegExp` objects for handling text data.
The primitive data type for representing text. A string is an immutable sequence of characters. JavaScript provides many built-in methods for manipulation, searching, and extracting parts of a string.
const text = 'Hello, World!'; text.slice(0, 5); // 'Hello'
A string is a sequence of characters, each with its own index. We can access and manipulate these characters based on their position.
Hello, World!
Index:
Character:
The object for representing **regular expressions**, which are patterns used to match character combinations in strings. It's a powerful tool for complex searching, replacing, and validation.
const pattern = /world/i;
pattern.test('Hello, World!'); // true
A regular expression is a pattern-matching engine. It scans a string and highlights all parts that match its rules.
String: The quick brown fox jumps over the lazy dog.
Pattern: /fox/
