Working with APIs is an essential skill for any web developer. APIs (Application Programming Interfaces) allow different software applications to communicate with each other.

When working with APIs, we use AJAX (Asynchronous JavaScript and XML) to send and receive data from a server without reloading the entire web page. AJAX allows us to update specific parts of a web page dynamically.

Let's take a look at an example that demonstrates how to interact with an API using AJAX:

1// Working with APIs
2
3function fetchData() {
4  const url = 'https://api.example.com/data';
5  const request = new XMLHttpRequest();
6
7  request.open('GET', url);
8  request.onload = function() {
9    if (request.status === 200) {
10      const data = JSON.parse(request.responseText);
11      // Use the data here
12    }
13  };
14
15  request.send();
16}

In this example, we define a function fetchData that sends a GET request to https://api.example.com/data. Once the request is complete, the onload event is triggered, and we can access the response data using request.responseText.

Using the JSON.parse method, we can convert the JSON response into a JavaScript object and then manipulate and use the data as needed.

Working with APIs opens up a world of possibilities for web development. Whether you are retrieving data from popular APIs like Google Maps or creating your own API, understanding the fundamentals of working with APIs is crucial.

for (let i = 1; i <= 100; i++) {

  if (i % 3 === 0 && i % 5 === 0) {

    console.log('FizzBuzz');

  } else if (i % 3 === 0) {

    console.log('Fizz');

  } else if (i % 5 === 0) {

    console.log('Buzz');

  } else {

    console.log(i);

  }
