Deciding on the Best Coding Language to Learn First
Choosing your first programming language as a beginner can seem daunting, but it doesn't have to be! Here are some of the most popular and beginner-friendly options to consider.
The Simplicity of Python for Beginners
Python is often recommended as the best first language for new coders because of its simple, easy-to-read syntax. Key advantages include:
High-level language that reads similarly to English
Lots of built-in functionality so you can focus less on nitty-gritty details
Huge community support for beginners with extensive tutorials and documentation
Versatile for uses like data analysis, machine learning, web backends, and more
With Python, you can start building usable programs quicker than lower-level languages. This helps beginners gain confidence and progress to more complex coding concepts.
HTML and CSS: The Building Blocks of Web Development
While not programming languages per se, HTML and CSS are essential for web development. Learning them early allows you to:
Understand the structure and styling of web pages
Quickly build basic websites as you progress to other languages like JavaScript
Gain a solid foundation before diving into full stack development
With HTML providing the content structure and CSS the visual styling, they work hand-in-hand for web presentation. Many coding apps and courses use projects like designing websites to teach programming basics to beginners.
JavaScript: A Versatile Language for Web and Beyond
JavaScript may have a confusing name, but it's an extremely versatile scripting language that runs practically everywhere - especially in web browsers. With JavaScript you can:
Add dynamic interactivity to websites
Build full stack web apps by combining with HTML/CSS

As one of the core languages of web development, JavaScript is a must-learn for aspiring coders. The prevalence of browser-based coding apps makes JavaScript readily accessible for beginners getting started with programming concepts.
Exploring Other Languages: C++ and SQL
While less common for absolute beginners, C++ is powerful for system-level programming like operating systems and games. And to store/access data, SQL provides the foundations for database management used in dynamic websites. The best first language depends on your goals - web development, software engineering, data science, etc. But popular beginner-friendly picks like Python, HTML/CSS, and JavaScript open lots of doors.
Programming Basics: Starting with Core Concepts
Programming languages all have fundamental building blocks in common that form the foundation for writing code. Mastering these core concepts is essential for coding beginners looking to gain competency.
Variables and Data Types: Storing Information
When learning to program, one of the first things you need to understand is how to store, reference, and manipulate data. This is done using variables.
A variable acts as a container for information that can be referenced and updated in a program.
You give each variable a custom name to represent what kind of data it holds, like userName, age, or totalCost.
Variables have an associated data type that determines what type of data they can store, like numbers, text, or true/false values. Common data types include:
int - whole numbers
double - decimal numbers
string - text
boolean - true/false logical values
When you want to work with a variable's data, you simply reference it by name. For example, you'd write userName = "Mary" to store the text "Mary" in the userName variable.
Understanding how to declare, initialize, and manipulate variables is essential to storing, accessing and modifying data in any program you write as a coding beginner.
Control Structures: Directing the Flow
The order in which statements execute in a program is called control flow. Control structures give you greater control over this flow to conditionally execute code or repeat blocks of code. The two most common control structures are:
Conditional statements - These allow you to check logical conditions and execute different code blocks based on the outcome. For example:
if (score > 10) {
print("You won!");
} else {
print("Try again");
}
Loops - These allow you to repeat a block of code multiple times. For example:
for (int i = 0; i < 5; i++) {
print(i);
}
This prints the numbers 0 to 4. Mastering control structures is key to directing how programs execute and dynamically responding to different conditions.
Functions and Modular Coding
A function is a reusable block of code that can be "called" from multiple places in a program. Functions promote modular code by allowing you to break complex tasks down into smaller, named steps. For example, you can encapsulate the logic to calculate sales tax in a calculateTax() function instead of repeating the same tax formula everywhere. Benefits of using functions:
DRY code - Don't Repeat Yourself
Reusability - Functions can be called anywhere
Readability - Gives names to steps
Encapsulation - Hides complex details
As programs get more advanced, functions become critical for managing complexity.
Understanding Syntax and Semantics
When learning a programming language, you need to understand both its syntax and semantics:
Syntax refers strictly to the structural rules of the language - the proper way to write code so the computer can interpret it. Mismatched braces or incorrect punctuation will lead to syntax errors.
Semantics refers to what your code instructions actually mean and how they are interpreted to influence program behavior. Two syntactically correct statements may produce different results based on their semantic meanings.
Gaining an understanding of both syntax rules as well as the semantics of keywords, data types, functions, etc. is crucial to writing code that functions as expected. Starting out, focus first on writing syntactically correct code and then learn how language semantics impact resulting values, state changes, and program flow.
