Introduction
This section introduces you to the basic concepts.
We will cover topics such as syntax, data types, and more.
let x = 10;
- Understand basics
- Key concepts
Getting Started
To begin, you need a proper environment setup.
This guide walks you through the steps.
npm install
- Install necessary packages
- Configure IDE
Variables
Variables are containers for storing data values.
Different programming languages have different ways of declaring variables.
var x = 5;
- Declare variables
- Initialize variables
Functions
A function is a block of code designed to perform a particular task.
Functions are reusable and can be called with different inputs.
function greet() { console.log("Hello!"); }
- Function declaration
- Function invocation
Loops
Loops are used to run the same block of code multiple times.
They are an essential part of any programming language.
for (let i = 0; i < 5; i++) { console.log(i); }
- For loops
- While loops
