In JavaScript, the switch statement is a control structure that allows different actions to be performed based on the different values of a variable. This structure helps avoid using multiple if-else statements, making the code cleaner and more readable. Here’s how the switch statement works in JavaScript, along with examples: switch(expression) { case value1: //…
In the JavaScript programming language, there are many situations where you may need to repeat certain operations. One of the most commonly used methods in such cases is the “for” loop. The for loop is used to repeat a block of code as long as a specific condition is true. Basic Structure of the For…
The for…in loop in JavaScript is used to iterate over the properties of an object. This loop scans all the properties of an object and returns each property one by one. It’s important to note that the properties are unordered, so the order of object properties is not guaranteed. Here’s how to use the for…in…
In JavaScript, there are various methods to iterate over arrays and other iterable objects. One of these methods is the For…Of loop. In this article, we will learn how to use the For…Of loop in JavaScript and when it should be preferred. What Is the For…Of Loop? The For…Of loop is a construct used to…
JavaScript is a widely used programming language in the world of web development. One of the loops provided by JavaScript is the “while” loop. In this article, I will explain the basics of the while loop in JavaScript and share some usage examples. What is a While Loop? A while loop is used to repeatedly…
Loops in JavaScript are essential constructs for performing repetitive tasks. However, there are situations where you need to control the loop based on certain conditions. This is where the “break” and “continue” statements come into play. The break Statement The break statement is used to exit a loop before it completes all iterations or moves…
In JavaScript, Iterables are structures that allow us to iterate over the elements of an object sequentially. This structure is similar to an array in that it connects elements together, but unlike an array, it can be used in a broader range of scenarios. Iterable and Iterator Concepts An Iterable is a feature that indicates…
In JavaScript, there is a data structure called a Set that is used to store and handle unique values. Sets hold unique values and do not allow duplicate values. In this article, we will show how JavaScript Sets are used and how they work. Creating a Set Sets are defined by creating a new Set…
In JavaScript, the Set object is a data structure that represents a collection of unique values. Set methods provide various functions to process and manage this collection. In this blog post, we will explain the Set methods available in JavaScript and demonstrate each with example code. This method adds a new value to a Set…
JavaScript offers developers various structures for data management. One of these structures is the “Map” data structure. A Map is a powerful tool that makes it easy to store key-value pairs and perform operations efficiently. In this article, we will explore JavaScript Maps in detail and demonstrate their usage with example code snippets. What is…
