Now Learn JavaScript Programming Language With Microsoft

icrosoft has released a new series of video tutorials on YouTube for novice programmers to get a hands-on renowned programming language — JavaScript.

This isn’t the first attempt by Microsoft to come up with video tutorials by beginner programmers. The company also has a series of YouTube tutorials on Python for beginners.

For JavaScript, Microsoft has launched a series of 51 videos as ‘Beginner’s Series to JavaScript,’ for young programmers, developers and coders who are interested in building browser applications using JavaScript. These video tutorials will also help programmers and coders to use relevant software development kits (SDKs) and JavaScript frameworks, such as Google’s Angular.


“Learning a new framework or development environment is made even more difficult when you don’t know the programming language,” stated on the Microsoft Developer channel on YouTube. “Fortunately, we’re here to help! We’ve created this series of videos to focus on the core concepts of JavaScript.”

It further stated — while the tutorials don’t cover every aspect of JavaScript, it indeed will help in building a foundation from which one can continue to grow. By the end of this series, Microsoft claims that the novice programmers will be able to work through tutorials, quick starts, books, and other resources, continuing to grow on their own.

Learning JavaScript: for Loops

In this article I’m going to cover the different forms of the for loop that are available in JavaScript. There is the general for loop, the for..in loop, and the for..of loop. I will describe how each loop works and when is the right time to use each loop type.

I am leaving out the Array.forEach loop as it is specialized for arrays and requires some knowledge of functions I haven’t covered yet.

The General for Loop

The first form of for loop I want to discuss is the general for loop that is standard in most programming languages. This loop is used in situations where you know in advance how many times you want the loop to iterate, as opposed to while loops, which should be used primarily when the number of iterations is unknown when the program is written, such as when you’re processing an unknown quantity of data or records in a file.

The syntax template for the general for loop is:

for (loop-variable-init; condition; loop-variable-modification) {

statement(s);

}

The loop variable is a variable that is initialized, tested, and then modified until it causes the condition to become false. Here is a simple example of a for loop that prints the numbers 1 through 10:

for (let i = 1; i <= 10; i++) {
  putstr(i + " ");
}

The output from this program is:

1 2 3 4 5 6 7 8 9 10

Let’s see how this loop works with an array:

let names = ["Terri", "Meredith", "Allison", "Mason"];
for (let i = 0; i < names.length; i++) {
  putstr(names[i] + " ");
}

This program outputs:

Terri Meredith Allison Mason

You can have more than one statement in the loop body. The following program accepts input from the user and displays the sum of the 5 numbers entered:

let total = 0;
let number = 0;
const numEntries = 5;
for (let i = 1; i <= numEntries; i++) {
  putstr("Enter a number: ");
  number = parseInt(readline());
  total += number;
}
print("The total is: " + total);

Here is the output from one run of this program:

Enter a number: 1
Enter a number: 2
Enter a number: 3
Enter a number: 4
Enter a number: 5
The total is: 15

The Most Important Programming Lesson I Ever Learned

In the fall of 2012, I walked into my graduate advisor’s office and asked her which computer science class she recommended for me to enroll in. I explained that I was a complete novice in programming. She suggested Introduction to C Programming.

After attending a few lectures, I discover that the majority of the students I spoke to in this introductorycourse had some prior experience in programming.

Six weeks and 80 hours of work later, I dropped the course.

Enter spring semester of 2013. I enrolled in an easier computer science course, Introduction to Computer Programming via the Web. I breezed through the first quarter of the course, executing HTML and CSS with ease. Then, we started Javascript (JS). That feeling of constant anxiety and stress from my previous computer science course returned in full fashion. It was too late in the semester to drop the course, so I asked a friend for help.

Learning JavaScript: Data Types and Variables

Image for post

To paraphrase the title of an old computer science textbook, “Algorithms + Data = Programs.” The first step in learning a programming language such as JavaScript is to learn what types of data the language can work with. The second step is to learn how to store that data in variables. In this article I’ll discuss the different types of data you can work with in a JavaScript program and how to create and use variables to store and manipulate that data.

JavaScript Data Types

Unlike a compiled programming language, JavaScript does not require you to declare the data type of a variable. However, internally, JavaScript keeps track of the type of data being stored in a variable.

The three fundamental types of data (also known as primitives) you can use in a JavaScript program are:

number: numeric values such as 100 or 3.14159

string: Textual data, which can include numbers and symbols

boolean: true or false values

There are other primitive types (BigIntSymbol, and undefined) but they are not important for your beginning education in JavaScript. There are three other data types in JavaScript — objectnull, and function — but I will also save the discussion of these types for another time.

Literal Data

When data is encountered in a program, that data is said to be literal data. For example, if I write:

print(100);

The value 100 is called a number literal. If I write:

print("Hello, world!");

The phrase “Hello, world!” is a string literal. Literals are found throughout a program and I needed to describe what literal data is to distinguish it from a variable, which is just a name for a storage location in memory that can hold data.

Determining the Data Type of a Literal

You can see what the type of a literal is by calling a special function: typeof. This function returns the type of data passed into it. Here are some examples of calling the typeof function on some literal data:

typeof(100); // returns "number"
typeof("hello"); // returns "string"
typeof(false); // returns "boolean"

As you become more experienced in JavaScript programming, you will find the typeof function useful for avoiding all types of logic errors in your programs.
