Find the Largest Among Three Numbers in JavaScript.

This tutorial will explain how to find the largest number among the three numbers provided in JavaScript. We can either use the Conditional Operators and if…else statement or the in-built Math.max() function of JavaScript.

Example 1: Using Conditional Operators and if…else statement.

// program to find the largest among three numbers

function largestNumber(x, y, z) {
  max = 0;
  if (x > y)
  {
    max = x;
  } else
  {
    max = y;
  }
  if (z > max) 
  {
    max = z;
  }
  return max;
}

console.log(largestNumber(10,100,1000));
console.log(largestNumber(55,6,78));
console.log(largestNumber(1,-22,-33));

Output

1000
78
1

Example 2: Using Math.max()

Syntax

Math.max(x, y, z);

// program to find the largest among three numbers

console.log(Math.max(10,100,1000));
console.log(Math.max(55,6,78));
console.log(Math.max(1,-22,-33));

Output

1000
