In this article, we are going to learn how to add Two Numbers in JavaScript. Adding two numbers in JavaScript involves performing arithmetic addition on numeric values, resulting in their sum.
There are several methods that can be used to Add Two Numbers in JavaScript, which are listed below:
- Using + Operator
- Using function
- Using Arrow function
- Using Addition Assignment (+=) operator
We will explore all the above methods along with their basic implementation with the help of examples.
JavaScript Program to Add Two Numbers using + Operator
In this approach we add two numbers in JavaScript involves using the + operator to perform arithmetic addition on numeric variables, resulting in their sum.
Syntax:
x + y;
Example: In this example, we are adding two numeric values by using the + operator.
Javascript
let num1 = 10; let num2 = 10; let sum = num1 + num2; console.log("Sum :", sum); |
Sum : 20
JavaScript Program to Add Two Numbers using function
In this approach, we are adding two numbers using a function in JavaScript involves defining a custom function that takes two parameters, adds them, and returns the result.
Syntax:
function additionFunction(a, b) {
return a + b;
}
Example: In this example we are using the above-explained approach.
Javascript
function additionFunction(a, b) { return a + b; } let num1 = 5; let num2 = 10; let sum = additionFunction(num1, num2); console.log("Sum of given numbers is :", sum); |
Sum of given numbers is : 15
JavaScript Program to Add Two Numbers using Arrow function
Adding two numbers using an arrow function in JavaScript involves creating a concise function syntax that adds parameters and returns the sum.
Syntax:
let addition = (a, b) => a + b;
Example: In this example we are using arrow function to add two numbers.
Javascript
let addition = (a, b) => a + b; let num1 = 25; let num2 = 25; let sum = addition(num1, num2); console.log("Sum of given numbers is :", sum); |
Sum of given numbers is : 50
JavaScript Program to Add Two Numbers using Addition Assignment (+=) Operator
In this approach we use Addition Assignment (+=) operator in which operator Sums up left and right operand values and then assigns the result to the left operand.
Syntax:
Y += 1 gives Y = Y + 1
Example: In this example we are using the above-explained approach.
Javascript
let num1 = 15; let num2 = 10; // Equivalent to num1 = num1 + num2 num1 += num2; console.log("Sum of the given number is :", num1); |
Sum of the given number is : 25
