Introduction to Programming
Welcome to Introduction to Programming. We'll be taking you through this series consisting
of 21 different segments that hope to cover the basics of computer programming, which can
apply to any and all programming languages you might want to learn.
We'll be starting with the simplest question of what is programming. And from there, we'll
move on to more complex topics such as variables, data types, and functions.
What is Programming?
Programming is the process of designing, writing, testing, and maintaining computer
programs. A computer program is a set of instructions that a computer follows to perform a
specific task. These instructions are written in a programming language that the computer
understands.
Programming can be used to create a wide variety of applications such as websites, mobile
apps, video games, and much more.
Variables and Data Types
Variables are used in programming to store data. Data can be of different types such as
numbers, text, and booleans. In programming, it's important to understand the different data
types and how to use them.
Numbers: Used for numeric values such as integers and decimals
Text: Used for strings of characters such as names and sentences
Booleans: Used for true/false values
Functions
Functions are used in programming to perform specific tasks. They are blocks of code that can
be called upon to perform a specific action. Functions can take in parameters and return
values.
Here's an example of a function:
function addNumbers(num1, num2) {
return num1 + num2;
}
let sum = addNumbers(5, 10);
console.log(sum); // Output: 15
