Capitalize

const { capitalize } = require('captialize');

console.log(capitalize('hello world')); // Output: "Hello World"
console.log(capitalize('hello world', { every: false })); // Output: "Hello world"
console.log(capitalize(''));      // Output: ""
console.log(capitalize(null));    // Output: ""

Case Conversions

The library also includes standard case conversion utilities:

const { 
  camelCase, 
  pascalCase, 
  snakeCase, 
  kebabCase, 
  titleCase 
} = require('captialize');

// camelCase
console.log(camelCase('Hello World')); // "helloWorld"
console.log(camelCase('--foo-bar--')); // "fooBar"

// PascalCase
console.log(pascalCase('hello world')); // "HelloWorld"

// snake_case

console.log(snakeCase('Hello World')); // "hello_world"

// kebab-case
console.log(kebabCase('hello_world')); // "hello-world"
console.log(kebabCase('camelCase')); // "camel-case"
