Add a Sort button for an SPA in JS using ES6

very simple. I have already done the main work. Need a JS person to add a sort button that will sort out all the recipes in a recipe add as a dropdown on the main page and, attach a document explaining the code flow. Please use ES6 principles. I need this quickly. I have a github link but, the project is private now, and I can add you as a collaborator as soon as it is awarded. I have the [login to view URL] page.
