Jun 2, 2011 · Number.prototype.even = function() { if (this % 1 !== 0) { return null } else { return (this & 1) === 0 } } Number.prototype.odd = function() { if (this % 1 !== 0) { return null } else { return (this & 1) !== 0 } }

Nov 30, 2014 · You need to use for loop to enumerate list, then check if the index is odd or even by using (i % 2 > 0) condition and apply the ternary operator as below. list[i].style.backgroundColor = (i % 2 > 0) ? "#CCFFCC" : "#CCFFFF";

4 days ago · 5. Using the Ternary Operator. The Ternary Operator is a shorthand for the if…else statement. It takes three operands: a condition, a result for true, and a result for false. This can be used to check whether a number is even or odd in one line. Syntax. condition ? expr1 : …

Feb 16, 2011 · Use the bitwise AND operator. return ( x & 1 ) ? "odd" : "even"; document.getElementById("result").innerHTML = "Number " + argNumber + " is " + oddOrEven(argNumber); If you don't want a string return value, but rather a boolean one, use this:

Feb 27, 2024 · Inside the function, we use the ternary operator to check if the number is even or odd. If the number modulo 2 equals 0 (meaning it's divisible by 2 with no remainder), then the condition evaluates to true, and the string "even" is assigned to the result variable.

Using the ternary operation, we pass it to an odd-even check function where the bitwise XOR logic is checked and a boolean value is returned. If it is true, we display that the number is "even" or else the number is "odd".

Mar 10, 2022 · The odd or even number check function can also be written using the ternary operator. The syntax is as follows: statement : returnIfTrue : returnIfFalse . Note that because a ternary statement requires a returnIfFalse expression, it is only applied to the check of whether a number is even or odd:

Sep 4, 2023 · You can check if a number is even or odd in JavaScript by using the modulo operator (%). It returns the remainder when one number is divided by another. If a number is divisible by 2 with no remainder, it is even.

Write a function to check if a number is odd or even. If the number is even, return "Even" ; otherwise, return "Odd" . For example, if num = 4 , the expected output is "Even" .

Jan 20, 2024 · Following is a simple JavaScript code that uses the modulo operator (%) and function to check if a number is odd or even, along with its output and a brief explanation: if (number % 2 === 0) { return "It is Even Number"; } else { return "It is Odd Number"; The program defines a function named checkOddOrEven that takes one parameter, number.
