In JavaScript, a Set is a built-in object that allows you to store a collection of unique values. Sets are part of ES6 (ECMAScript 2015) and are widely used for managing unique data efficiently. Unlike arrays, Sets automatically filter duplicate values, making them ideal for scenarios where uniqueness is essential. What Is a JavaScript Set? … Read more

What Are Iterables? Iterables are objects that implement the @@iterator method, making their data accessible in a sequential manner. These objects conform to the Iterable Protocol, which defines how elements within the object can be accessed and iterated over. Common examples of iterable objects in JavaScript: How Iterables Work Iterables use an internal method called … Read more

What is JavaScript Break Statement? The break statement in JavaScript provides a way to exit a loop or switch statement prematurely when a specific condition is met. It is a control flow mechanism used to stop the execution of code inside a loop or switch without waiting for the natural termination. This makes your code … Read more

What is The JavaScript While Loop The while loop in JavaScript is a fundamental control structure that repeatedly executes a block of code as long as a specified condition is true. Unlike loops that iterate over collections (for…of) or indexes (for), the while loop is ideal for scenarios where the number of iterations isn’t predetermined … Read more

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
