In this tutorial, we will learn how to perform integer division and get the remainder in JavaScript. The division operator (/) returns the quotient of its operands, where the dividend is on the left, and the divisor is on the right. When another splits one operand, the remainder operator (%) returns the residual. It always takes the dividend sign. In the operation x% y, x is known as the dividend, and y is known as the divisor. If one of the operands is NaN, x is Infinity, or y is 0, the operation returns NaN. Otherwise, the dividend x is ... Read More
