Learn about TypeScript Types in Programming

This story is about types in TypeScript which is a typed superset of JavaScript that compiles to plain JavaScript. I will go to more detail to explain some terms below.

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.

Learn to Program Better with The Weekly Spot Drill

Most of us have fallen into this trap. We’re so focused on learning a topic or honing a skill that we don’t touch previously learned information for weeks or months.

Web development is a classic example. There are many technologies and topics to learn, and most of us learn them sequentially. You focus on CSS for a while, then put it on hold to learn the intricacies of React. Or take problem-solving. You focus exclusively on problems that involve arrays. Then strings. Then hash tables.

There’s a problem with this approach. Soon comes the day when we need to apply knowledge that we learned a few weeks ago. And we can’t, at least not easily. We’ve forgotten what we’ve learned. We’ve lost our edge.

It doesn’t have to be this way. In part, the solution involves using Anki flashcards on a daily basis. It’s a topic I’ve written about before, and it’s a great way to keep information fresh and top of mind.

The other part of the solution is what I call the “weekly spot drill.” Once per week, work on a project or problem related to something you previously learned — and unrelated to what you’re currently learning about or working on.

If you’re learning JavaScript right now, solve a problem in Python. If you’re solving tons of problems that involve arrays, pick one that involves strings.

The weekly spot drill will keep your skills sharp — ensure that you’re ready, not rusty — and deepen your knowledge. That’s because you’ll uncover another layer each time you revisit a topic. Plus, this practice will teach you to pivot: to use the best tool to solve the problem, not necessarily the one you’re currently focused on.

An example from the game of baseball drives home the point.

13 Reasons Why It’s High Time to Start Learning to Program

Software development is something that is gaining popularity at lightning speed with the development of technology. The demand for regular developers is high compared to most other mainstream professions. But, what are the other reasons for learning to code?

Given my experience as a software engineer and Java tutor, I’ve come up with many reasons, and, in this blog post, I am going to share them with you. Hope they will lead you to an informed decision.

1. Generous Salary

Salary is a frequently discussed subject in a programming environment. Compared to many other industries, software engineering allows specialists to receive a way higher average wage.

To avoid being verbose and prove that you are a future high-demand expert, I will give you real numbers based on data from Glassdoor job and recruiting website. The salary rate is the average between the length of service and all geographical data. It also depends on the coding language you are mastering.

Learning C++: Variable Scope

Variable scope refers to the ability of a variable to be “seen” in a program. A variable is seen if, in a specific place in a program, the programmer has access to that variable’s value. There are levels of scope in a C++ program, with the level of scope determining how widely a variable can be seen in a program. In this article I’m going to discuss the different levels of variable scope and why they are important.

The Scope Levels

Here are the three levels of scope in a C++ program: global, local, and block. Global is the most expansive scope and means that any variable declared with global scope can be seen in any place in a program. Local scope usually refers to a variable defined in a function and can be seen throughout that function, but not in other functions. Block scope means a variable was defined within a block of code, such as a for loop or an if statement.

With these definitions out of the way, let’s look at how these different scope levels affect a C++ program.

Global Scope

A variable that has global scope can be seen in any other part of a C++ program, from a function definition to a block of code. A variable that is defined outside of the main function is a global variable.

Here is an example that demonstrates how global scope works:

#include <iostream>
using namespace std;

// global space
int number = 1;
void showValue() {
  cout << "Number accessed from a function: " << number << endl;
}
int main ()
{
  showValue();
  cout << "Number accessed from the main function: "
       << number << endl;
  for (int i = 1; i <= 1; i++) {
    cout << "Number accessed from a block: " << number << endl;
  }
  return 0;
}
