Usage

Import the desired functions from the library and use them in your JavaScript code:

javascript

const {
    reverseString,
    capitalizeString,
    countWords,
    truncateString,
    camelCase,
    kebabCase,
    snakeCase,
    isPalindrome,
    removeWhitespace,
    repeatString,
    replaceSubstring,
    randomString
} = require('simple-string-utils');


const reversed = reverseString('hello world');
console.log(reversed); // Output: 'dlrow olleh'

const capitalized = capitalizeString('hello world');
console.log(capitalized); // Output: 'Hello world'

const wordCount = countWords('hello world');
console.log(wordCount); // Output: 2

const truncated = truncateString('hello world', 5);
console.log(truncated); // Output: 'hello...'

const camelCased = camelCase('hello world');
console.log(camelCased); // Output: 'helloWorld'

const kebabCased = kebabCase('hello world');
console.log(kebabCased); // Output: 'hello-world'

const snakeCased = snakeCase('hello world');
console.log(snakeCased); // Output: 'hello_world'

console.log(isPalindrome('A man, a plan, a canal, Panama!')); // Output: true
console.log(removeWhitespace('Hello, World!')); // Output: 'Hello,World!'
console.log(repeatString('abc', 3)); // Output: 'abcabcabc'
console.log(replaceSubstring('Hello, World!', 'World', 'Universe')); // Output: 'Hello, Universe!'
console.log(randomString(10)); // Output: A random string of 10 characters, e.g., 'Gs8fhKj1Mq'
