JavaScript AJAX JSON API for Beginners Learn JavaScript ES6

Explore json data basics, including name-value pairs, objects and arrays, and validate json with json lint while testing with the randomuser.me open api in JavaScript.

Learn to fetch JSON data with the JavaScript Fetch API, convert responses to usable JavaScript objects, and extract fields like email from API results.

Explore JavaScript objects and JSON data, learning how to create and access name–value pairs, properties, and methods, log objects to the console, and distinguish JSON from JavaScript.

Explore JSON and JavaScript objects, noting JSON keys must be quoted while JavaScript object keys may be unquoted, and access properties with dot or bracket notation.

Learn to output object values to a web page by creating divs, selecting DOM elements (getElementById or querySelector), and updating textContent with a first name and last name.

Learn how to model data with arrays and objects, access values via dot and bracket notation, and iterate through an array of items such as cars with colors.

Learn how to structure arrays of objects and loop through them with for loops and for each, accessing properties like first name and age, and logging results to the console.

Explore advanced looping options in JavaScript, including for...in and map, to iterate objects like my object with people and places, output property names and values, and rebuild arrays or objects.

Learn to convert a string into an object and back with JSON.parse and JSON.stringify, enabling cookie and local storage data handling and simple object updates.

Explore how Ajax enables API requests and JSON data exchange without page refresh, using the XMLHttpRequest object, readyState changes, and DOM updates to render server responses.

demonstrate making xhr ajax requests to api endpoints, parse json to extract first and last names from random user data, and display results in page elements with loops.

Fetch and display 10 random user results from the random user API using Ajax, looping through the response text and rendering names and images on the page.

Connect to the random user API with fetch, retrieve ten results, and display each person's name and thumbnail on the page using a for each loop.

Learn how to use the JavaScript map method to create a new array from existing data, reconstruct objects, and extract first and last names for cleaner output.

Set up a local JSON server with node and npm to practice ajax requests, simulate a backend with JSON data and a database, and run across Windows, Mac, and Linux.

Install and verify node and npm, update npm globally, and run a JavaScript file with node to print hello, preparing to set up a local JSON server.

Install json-server globally with npm, and create a db.json file as your database. Practice ajax requests (get, post, put, patch, delete) against local routes for posts, comments, and profiles.

Explore how to test a json server with Postman, sending get, post, put, patch, and delete requests to update the database and view responses.

Learn to post data with fetch to a local JSON server, handling title and name inputs, setting the content-type to application/json, and displaying the response on the page.

Set up and run a Jason server as a node file, configure the database, router, and middleware, and launch the server on a specific port.

Learn to run a json-server as a node file, configure a database, set up router and middleware, and launch the server on a chosen port.

Wrap up the final project by running the Jason server, updating and adding data to the JSON data source, and enabling in-line edits with event listeners and fetch-based updates.

Learn to update a Jason database using fetch with a put request, supplying id, first and last in the body, and setting content-type header to application Jason.
