Incrementing & Decrementing Operators ➕➖ In JavaScript, incrementing and decrementing are operations used to increase or decrease a variable’s value by 1. These operators are ++ (increment) and — (decrement). Example: let x = 5; x++; // Increment by 1, x becomes 6 x–; // Decrement by 1, x becomes 5 While Loops 🔄 A while loop repeatedly executes a block of code as long as the given condition evaluates to true. Example: let i = 0; while (i < 5) { console.log(i); // Outputs: 0, 1, 2, 3, 4 i++; } For Loops 🔄 A for loop is a […]

Guide on JavaScript operators and flow control, including if statements, comparison operators, and logical operators.

JavaScript Operators & Flow Control: Master in 60 Seconds ⏱ First 100 characters:Learn JavaScript operators and flow control quickly! Understand equality, if statements, and logical operators. 🚀 Loose Equality vs. Strict Equality 🆚 In JavaScript, you can compare values using loose equality (==) or strict equality (===). Loose equality (==) compares values after type coercion (converts them to the same type). Strict equality (===) compares both the value and the type. Example: console.log(5 == “5”); // true (type conversion happens) console.log(5 === “5”); // false (different types) If Statements 📝 The if statement in JavaScript evaluates a condition and executes […]

Introduction to Functions ⚙️ In JavaScript, functions are blocks of code designed to perform a specific task. Functions allow you to write reusable code, making your programming more efficient and organized. Understanding how to define and call functions is a fundamental skill for any JavaScript developer. Defining and Calling Functions in JavaScript 📝 A function in JavaScript is defined using the function keyword, followed by the function name, parameters (if any), and the code to execute. You can call a function by simply using its name and passing any necessary arguments. Example of defining and calling a function: function greet(name) […]

Tutorial of JavaScript data types: number, string, boolean, null, and undefined.

Introduction to JavaScript Data Types: Number, String, and Boolean 🔢💬 In JavaScript, data types are fundamental building blocks used to define the type of a value. Every value in JavaScript is associated with a specific data type, such as Number, String, or Boolean. These types help JavaScript know how to treat and manipulate the value in the code. Numbers 🔢 JavaScript uses the Number data type for both integers and floating-point numbers. It allows arithmetic operations like addition, subtraction, multiplication, and division. Example: let num1 = 10; // Integer let num2 = 15.5; // Float console.log(num1 + num2); // Outputs: […]
