Conditionally Joining classNames using clsx Library in React

A tiny (228B) utility for constructing className strings conditionally.
Also serves as a faster & smaller drop-in replacement for the classnames module.

npm install --save clsx

import clsx from 'clsx';
 
// Strings (variadic)
clsx('foo', true && 'bar', 'baz');
//=> 'foo bar baz'
 
// Objects
clsx({ foo:true, bar:false, baz:isTrue() });
//=> 'foo baz'
 
// Objects (variadic)
clsx({ foo:true }, { bar:false }, null, { '--foobar':'hello' });
//=> 'foo --foobar'
 
// Arrays
clsx(['foo', 0, false, 'bar']);
//=> 'foo bar'
 
// Arrays (variadic)
clsx(['foo'], ['', 0, false, 'bar'], [['baz', [['hello'], 'there']]]);
//=> 'foo bar baz hello there'
 
// Kitchen sink (with nesting)
clsx('foo', [1 && 'bar', { baz:false, bat:null }, ['hello', ['world']]], 'cya');
//=> 'foo bar hello world cya'
