JavaScript provides several looping structures to handle iteration tasks efficiently. The for…of loop is a modern and intuitive way to iterate over iterable objects such as arrays, strings, maps and sets. Unlike for and for…in loops, the for…of loop focuses on values rather than indices or keys, making it ideal for clean and readable code. … Read more

What is the For…In Loop? The for…in loop iterates over all enumerable properties of an object. It works by accessing the keys (or property names) of the object, which can then be used to retrieve corresponding values. Unlike a traditional for loop, the for…in loop is specifically built for objects, though it can also be … Read more

What is a For Loop? A for loop is a control structure that repeats a block of code as long as a specified condition is true. It is particularly useful for executing repetitive tasks, such as iterating over arrays or performing calculations. Syntax for (initialization; condition; increment/decrement) { // Code to execute in each iteration} … Read more

What is a JavaScript Switch Statement? The switch statement evaluates an expression and matches it with a case. If a match is found, the associated code block runs. If no match is found, the default block (if provided) executes. Syntax switch (expression) { case value1: // Code to execute if expression === value1 break; case … Read more

What Are JavaScript if…else Statements? The if…else statement checks whether a condition is true or false. Based on the result, it decides which block of code to execute. Syntax if (condition) { // Code to execute if the condition is true} else { // Code to execute if the condition is false} Examples 1. Basic … Read more

What is JavaScript Comparisons? JavaScript comparisons allow you to compare values and determine the relationships between them. They return Boolean values (true or false) and are widely used in conditional statements, loops, and decision-making logic. In this guide, you will learn all about JavaScript comparison operators, their applications and examples to help you understand their … Read more

Whta is JavaScript Booleans? In JavaScript, Booleans represent one of two values: true or false. They are essential in programming because they drive decision-making and logic. Booleans are commonly used in conditional statements, loops and comparisons to control the flow of a program. Boolean Values in JavaScript A Boolean has only two possible values: Example: … Read more

What is JavaScript Random Method? The Math.random() method in JavaScript generates a random decimal number between 0 (inclusive) and 1 (exclusive). While this method is simple, it is a foundational tool for many real-world applications, such as gaming logic, data simulations, password generators and more. How Math.random() Works The Math.random() method generates a pseudo-random number. … Read more

Why Use the Math Object? The Math object is essential for tasks like: Whether you’re working on animations, gaming logic or complex algorithms, the Math object simplifies calculations. Key Properties of the Math Object The Math object includes several constants that represent important mathematical values: Property Value Description Math.PI 3.141592653589793 The ratio of a circle’s … Read more

Overview of JavaScript Date Set Methods The Date object offers various set methods to change date and time values: Method Purpose Example Input setFullYear(year, month?, day?) Sets the year (optionally, month and day) 2025, 10, 15 setMonth(month, day?) Sets the month (0-11, where 0 = January) 6 (July) setDate(day) Sets the day of the month … Read more
