# How to find largest of three numbers using JavaScript ?

• Difficulty Level : Basic
• Last Updated : 28 Nov, 2022

In this article, we will find the largest of 3 given numbers using JavaScript.

We will do so by making use of the simple if-else statements in JavaScript. JavaScript is a front-end language that can print directly to the console as well as to the view page like .html.

Let us look at the console log outputs and the corresponding code.

#### Approach 1: Using the if-else statements

The if-else statements used for checking conditions will be used to compare the 3 numbers. The variables will be called x, y and z. We compare x with y and z, y with x and z, and z with x and y to see which is the largest number.

Example: In the example below it is first checked if x(=5) is greater than y(=10) and z (=15) which is false. Then the program checks if z(15) is greater than x(=5) and y (=10) which returns true and hence 15 is the largest.

## Javascript

 ``

Output:

`Z = 15 is the greatest`

There are multiple approaches to finding the largest of 3 numbers, let us have a look at the other approaches as well:

#### Method 2: Using the Math.max function

The Math.max() function returns the largest of the numbers given as input parameters, or -Infinity if there are no parameters. Our variables named x,y, and z are simply passed to Math.max() and we get the highest of the 3 numbers. This function can take multiple arguments and not just 3.

Example:

## Javascript

 ``

Output:

`15 is the greatest`
