$ npm i gender-api.com-client --save
try{var GenderApi =require('gender-api.com-client');var genderApiClient =newGenderApi.Client('your api key'); genderApiClient.getByFirstName('theresa',function(response){ console.log(response.gender); console.log(response.accuracy);}); genderApiClient.getByFirstNameAndCountry('john','US',function(response){ console.log(response.gender); console.log(response.accuracy);});}catch(e){ console.log('Error:', e);}
