Component library for React that uses observable state management and theme-able components.

/**
 * You can use this `camelCase` function to convert a string to camel case. For example:
 *
 * ```typescript
 * console.log(camelCase('foo bar'));       // Output: 'fooBar'
 * console.log(camelCase('hello-world'));   // Output: 'helloWorld'
 * console.log(camelCase('foo_bar_baz'));   // Output: 'fooBarBaz'
 * ```
 * @param str
 * @returns

  // Capitalize the first letter of each word after the first word
