In this tutorial, we will learn about the multiplication operator (*) in JavaScript. The multiplication operator is a binary operator which requires at least two operands to operate on. The multiplication operator simply multiplies the left operand with the right operand, or you can say that it simply increases the value of the left operand with the same value till the value of the right operand becomes zero. The example below will explain you everything − 3 * 2 = 6 OR 3 + 3 = 6 5 * 3 = 15 OR 5 + 5 + 5 = 15 ... Read More
