JavaScript(17)---Introduction to Requests

Introduction to Requests

One of JavaScript’s greatest assets is its non-blocking properties, or that it is an asynchronous language.

ADVANCED VERSION OF IT

REVIEW:

• JavaScript is the language of the web because of its asynchronous capabilities. AJAX, which stands for Asynchronous JavaScript and XML, is a set of tools that are used together to take advantage of JavaScript’s asynchronous capabilities.
• There are many HTTP request methods, two of which are GET and POST.
• GET requests only request information from other sources.
• POST methods can introduce new information to other sources in addition to requesting it.
• GET requests can be written using an XMLHttpRequest object and vanilla JavaScript.
• POST requests can also be written using an XMLHttpRequest object and vanilla JavaScript.
• Writing GET and POST requests with XHR objects and vanilla JavaScript requires constructing the XHR object using new, setting the responseType, creating a function that will handle the response object, and opening and sending the request.
• To add a query string to a URL endpoint you can use ? and include a parameter.
• To provide additional parameters, use & and then include a key-value pair, joined by =.
• Determining how to correctly write the requests and how to properly implement them requires carefully reading the documentation of the API with which you’re working.

What did I learn in this lesson? 

I did not learn too much on the coding part, however, I learned about a new way of using the codes. And this is actually pretty cool, and can be used in doing surveys.
