_.uniqueId([prefix='']) source npm package Generates a unique ID. If prefix is given, the ID is appended to it. Since 0.1.0 Arguments [prefix=''] (string): The value to prefix the ID with. Returns (string): Returns the unique ID. Example _.uniqueId('contact_'); // => 'contact_104'   _.uniqueId(); // => '105'
