Last active June 26, 2018 07:22
in JavaScript, functions are objects, so there is actually no overloading, but we can do encapsulations like this
function greet(firstname, lastname, language) {
language = language || 'en';
if (language === 'en') {
console.log('Hello ' + firstname + ' ' + lastname);
}
if (language === 'es') {
console.log('Hola ' + firstname + ' ' + lastname);
