How to Work with Strings in Object-Oriented JavaScript?

Estimated read time 1 min read

Here are a few ways to work with strings in object-oriented JavaScript:

  1. Using String objects: String objects have built-in methods for manipulating strings, such as toUpperCase(), toLowerCase(), indexOf(), and substring().
  2. Using template literals: Template literals allow you to interpolate variables into string, and also multi-line string.
  3. Using Regular Expressions: Regular expressions can be used to match and replace string patterns.

Example:

let string = "Hello World!";

// Using String object methods
console.log(string.toUpperCase());
console.log(string.toLowerCase());
console.log(string.indexOf("o"));

// Using template literals
let name = "John";
console.log(`Hello, ${name}!`);

// Using Regular Expressions
let pattern = /\w+/g;
console.log(string.match(pattern));
