Alchemy Options comes with some client-side helpers, available in the global alchemyOptions variable. Functions use the wonderful kew library as a light-weight promises polyfill.
Functions have been tested in Internet Explorer 10 and newer. All modern browsers should do just fine.
A light-weight(10Kb minified, NOT gzipped) script is registered as alchemy-options-client-scripts. Add it as a dependency if you want to use it, like so:
wp_enqueue_script( 'my-scripts', '/path/to/my-scripts.js', array( 'alchemy-options-client-scripts' ), '1.0', true );
