Takes a string and converts to camelCase

camelCase.js

/**
 * Convert string to camelCase.
 * Function will remove `,`, `_`, `-`, and `' '` from string.
 *
 * Note: Function does not strip numeric characters.
 *       A string like `hello 1world` would return `hello1world`
 *
 * @example
 *   camelCase('hello world') // returns 'helloWorld'
 *
 * @example
 *   camelCase('hello_world') // returns 'helloWorld'
 *
 * @example
 *   camelCase('hello-world') // returns 'helloWorld'
 *
 * @example
 *   camelCase('hello,world') // returns 'helloWorld'
 *
 * @example
 *   camelCase('__--HeLlO wOrLd--__') // returns 'helloWorld'
 *
 * @param {string} string - String to convert
 * @returns {string}
