Takes a string and converts to pascalCase

pascalCase.js

/**
 * Convert string to pascalCase.
 * Function will remove `,`, `_`, `-`, and `' '` from string.
 *
 * Note: Function does not strip numeric characters.
 *       A string like `hello 1world` would return `Hello1world`
 *
 * @example
 *   pascalCase('hello world') // returns 'HelloWorld'
 *
 * @example
 *   pascalCase('hello_world') // returns 'HelloWorld'
 *
 * @example
 *   pascalCase('hello-world') // returns 'HelloWorld'
 *
 * @example
 *   pascalCase('hello,world') // returns 'HelloWorld'
 *
 * @example
 *   pascalCase('__--HeLlO wOrLd--__') // returns 'HelloWorld'
 *
 * @param {string} string - String to convert
 * @returns {string}
