Fahrenheit to Celsius – JavaScript and AngularJS

You probably know how to convert Fahrenheit to Celsius in JavaScript but how would you display it on a web page?

Google has come up with a modern solution: AngularJS

AngularJS is a way to make your HTML more dynamic and it is easy to implement.

Take a look at my sample here:

Have fun testing it!

On Learning

“People that learn quickly only focus on the information and skills that matter – excuses don’t matter, and they are thought viruses.” – Kevin Horsley

“No time? Time is always there; you just need to schedule it.”

Dot Syntax

What is the meaning of the dot?
The dot signifies that we want to use something that’s inside something else.

console.log("log is inside of a console");"Tony de Araujo");
// search is a method which is inside of object myObject

Hope it helps!

Get your six lucky numbers with AngularJS

Hi dear reader,
If you have read my eBook Small Projects to Learn JavaScript – Drawing Six ‘Lucky’ Numbers
you’ll be pleased to know that I have converted the project into AngularJS.

AngularJS was not even mentioned in the book but I figured it was time to demonstrate a way of implementing AngularJS on the script and it is a cool implementation as you may see on the following link:

Happy coding!


Can we run JavaScript tests on the Windows command prompt?

Yes we can ( once we install Node.js on our machine).
Node.js was first published by Ryan Dahl in 2009 and could only run on Linux.In June 2011, Microsoft partnered with Joyent to help create a native Windows version of Node.js.
Node.js is a cross-platform runtime environment for server-side and networking applications. Once installed on Windows we can do lots of things with it, one of such benefits is to run JavaScript on the command prompt.

Installation only takes minutes. Please see my other article on how to go about it, from installation to testing JavaScript on the command line:

Happy first of September, everyone!

JavaScript, how to pass in data from the stack to the heap

One way to pass data from the stack to the heap is as an argument in a function call.

How to pass in data from stack to heap
In JavaScript, primitive data from a variable can be passed into a function as a copy, via a function argument which is given to a function parameter.

The parameter acts as the interface between stack and heap. In other words, the data in the variable and the data being passed into the function becomes independent of each other.

So even though a function resides in the heap, we are not pointing or passing by reference, we are actually cloning the data to be processed by the function, which is the same as passing by value (remember? like copying data into another variable or “adding”value).

If this intermediate level JavaScript subject interests you, I go into deeper detail on my eBook:
