Learn Asynchronous JavaScript – ASYNC JS, Save time by executing code over time. It doesn’t take a long time!
It’s hard to imagine a website that never sends any messages to analytics, 3rd party APIs, or databases where important information like user profile information and chat history are held.
You are the in-house developer at W&W Window Washers.
The owner’s eccentric son, Malachi Window, appears at your desk one afternoon in a flush.
“We’ve signed up with a new payment platform, one that will be less inclined to pry into our… affairs.” He says.
“Right,” you agree, with some hesitation.
“You need to update our website to go through that vendor. Send the client’s payment information to the vendor, and when the vendor’s API sends a message back, send the order to our supplier,” explains Malachi.
You fire up your computer and get to work, but
there’s a problem.
JavaScript code executes all at once. There is no wait keyword in JavaScript that pauses before the next line of code. How can we know if the vendor approves the payment information before sending a message to the supplier?
Did you know that without Asynchronous Code, none of these things can be accessed in JavaScript?
In this course, we’ll cover the 5 primary tools all developers need to write asynchronous JavaScript:
By the end of this course, you should feel comfortable using all these tools in projects, and you should be able to decide which tool makes the most sense for any given project.
Example of Javascript Codes.
“Either write something worth reading or do something worth writing.”
― Benjamin Franklin
“If we all did the things we are really capable of doing, we would literally astound ourselves.”
“Genius is one percent inspiration, ninety-nine percent perspiration.”
“We often miss opportunity because it’s dressed in overalls and looks like work.”
― Thomas A. Edison
“If you can’t explain it to a six-year-old, you don’t understand it yourself.”
“Anyone who has never made a mistake has never tried anything new.”
“Logic will get you from A to Z; imagination will get you everywhere.”
“Any fool can know. The point is to understand.”
― Albert Einstein
