Comparison Between AJAX and Ruby

Both of these pieces of code:

• Make an HTTP GET request to the same URL
• Parse the response (which is in JSON format) into datatypes (Hash for Ruby and Object for JavaScript)
• Retrieve the results array and iterate over each Star Wars character

Ruby

require "open-uri"
require "json"

response = open("https://swapi.co/api/people/").read
data = JSON.parse(response)
data["results"].each do |person|
  puts "#{person['name']}"
end

JavaScript

fetch("https://swapi.co/api/people/")
  .then(response => response.json())
  .then((data) => {
    data.results.forEach((person) => {
      console.log(person.name);
    });
  });

Step by Step

fetch("https://swapi.co/api/people/")

Get the raw data from the server in JSON format.

.then(response => response.json())

Take that raw data and turn it into an Object.

 .then((data) => {
   data.results.forEach((person) => {
     console.log(person.name);
   });
 });

Get the results array from the object and iterate over each element (Star Wars character) and print the name property to the console.
