A leap year is a year that is divisible by 4, but if it is also divisible by 100, it should be divisible by 400 to be a leap year. In this tutorial, we will write JavaScript programs to check …

In this tutorial, we’ll create a JavaScript program that generates a random number within a specified range using JavaScript’s built-in Math functions. Here’s a simple JavaScript program to generate a random number between a specified minimum and maximum value: // …

In this tutorial, we’ll create a simple calculator using JavaScript that can perform basic arithmetic operations: addition, subtraction, multiplication, and division. We’ll use the prompt() function for input and switch statement to handle different operations. Here’s the full code for …

Here are some JavaScript programs that check if a given number is a prime number. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. Example 1: Basic Prime Number Check …

The for loop is one of the most commonly used looping structures in JavaScript. It allows you to execute a block of code a specific number of times, based on a condition. It is typically used when you know beforehand …

The do…while loop in JavaScript is similar to the while loop, with one key difference: a do…while loop will execute the code block at least once, even if the condition is false. This is because the condition is evaluated after …

The while loop in JavaScript repeatedly executes a block of code as long as a specified condition evaluates to true. It is useful when you don’t know beforehand how many times you need to repeat a code block. Syntax of …

The switch statement in JavaScript is a control structure used to execute different code blocks based on the value of an expression. It is a more readable alternative to multiple if…else statements when dealing with multiple conditions. Syntax of switch …

In JavaScript, data types determine the type of value stored in a variable. JavaScript has both primitive data types (which include String, Number, Boolean, Undefined, Null, Symbol, and BigInt) and non-primitive data types (Object, Array, Function).   1. Primitive Data …
