Discover how to use JavaScript programming to check for an Evil Number, a mathematical curiosity where the binary representation of a number has an even count of ‘1’ bits. Dive into the world of programming and explore the properties of intriguing numerical concepts.

“Check if a number is a Harshad Number in JavaScript using a concise program. A Harshad (or Niven) Number is one that is divisible by the sum of its digits. Explore the code to identify and understand these interesting mathematical properties in JavaScript programming.

A leap year is a year that contains an extra day, making it 366 days long instead of the usual 365 days. It occurs approximately every four years to keep the calendar year synchronized with the solar year, which is the time it takes for the Earth to complete one orbit around the Sun.

A multiplication table, also known as a times table or multiplication chart, is a mathematical table that displays the products of multiplication for a specific range of numbers. It provides a structured representation of the multiplication facts.

Swapping two numbers means exchanging their values. In other words, if you have two variables A and B, swapping them would involve interchanging their values so that the initial value of A becomes the value of B, and vice versa.

The sum of digits refers to the result obtained by adding together all the individual digits of a given number.

A perfect number is a positive integer that is equal to the sum of its proper divisors (excluding the number itself). In other words, the proper divisors of a number are the positive integers that divide the number evenly, leaving no remainder, but are less than the number itself.

Prime factors are the prime numbers that divide a given number evenly, without leaving a remainder. In other words, they are the prime numbers that are factors of a given number.

A palindrome number is a number that remains the same when its digits are reversed. In other words, it reads the same forward and backward. For example, 121, 555, and 12321 are all palindrome numbers.

An odd number is an integer that is not divisible by 2, meaning it does not leave a remainder of 0 when divided by 2. In other words, an odd number cannot be evenly divided into two equal parts.

An even number is an integer that is divisible by 2, meaning it leaves no remainder when divided by 2. In other words, an even number can be divided into two equal parts.

Condensing a Number refers to summing its digits until a single-digit number is obtained.

An Armstrong number, also known as a narcissistic number, is a number that is equal to the sum of its own digits, each raised to the power of the number of digits.

To calculate the average of a set of numbers, you add up all the numbers in the set and then divide the sum by the total count of numbers in the set.

To determine the biggest of three numbers, you compare them to each other and identify the largest value.

Common divisors, also known as common factors, are numbers that evenly divide two or more given numbers. In other words, a common divisor is a number that is a factor of two or more given numbers.

JavaScript interview programs refer to programming questions or problems that are commonly asked in job interviews for positions that require knowledge of the JavaScript programming language. These programs are designed to test a candidate’s understanding of JavaScript concepts, problem-solving skills, and ability to write efficient and correct code.

Lets learn how to print the above star pattern using JavaScript Programming.
