How to use Multiplication Assignment Operator In Javascript

Q: How to use Multiplication Assignment Operator In Javascript

Functions are the building blocks of some specific code that carry out specific tasks. Using the function, we can multiply two numbers by passing parameters, and the function will then return the result of the multiplication.

Using Arrow function

Using for Loop

When multiplying a variable by a specific amount and returning the result to the variable, the multiplication assignment operator *= is a useful shorthand. In JavaScript, it is a compound assignment operator.

Example:

P = 10 
P *= 2 is equal to P = P*2 
So, now P will be 20.

Syntax:

varibale_name  *=  value/anotherVariable_name;

Example: This example is describing how we can multiply two number using multiplication assignment operator.

Javascript

// Creating a variable having value 20 
let a = 20; 
  
// Using multiplication assignment operator  
// Using value for multiplication 
a *= 10; 
  
// Printing the result 
console.log(a); // 10 
  
// Using another variable for mulitiplication 
let b = 2; 
a *= b; 
  
// Printing the result 
console.log(a); // 10

Output

200
400

JavaScript Program for Multiplication of Two Numbers

In this article, we are going to learn how we can multiply two numbers using JavaScript. Multiplying the two numbers in JavaScript involves performing arithmetic addition on numeric values, resulting in their sum.

JavaScript supports numeric data types. In JavaScript, both floating-point and integer numbers fall under the same “Number” type. Because JavaScript takes care of it for you, you don’t need to explicitly declare whether a number is an integer or a floating-point number. In order to avoid having to declare them separately, we can use a variable and assign it to any value.

Examples:

Let's take two numbers 
a = 4 , b = 10
 
Here a is multiplicand and  b is multiplier 
a * b = 4 * 10 = 40

These are the following ways by which we can multiply two numbers:
