class-names – Conditionally join CSS class names together

One of the packages I’ve been using a lot is classnames, a simple JavaScript utility for conditionally joining classNames together. Recently I stumbled upon @sindresorhus/class-names, a likewise package whose usage is very similar. import classNames from '@sindresorhus/class-names'; // Think of these like props of your React component … const props = { type: 'success', small: […]
