Find Largest of 2 and 3 Numbers (JavaScript)

Finding the largest among a set of numbers is a common introductory programming problem that demonstrates the use of conditional statements (if-else or if-else if-else) in JavaScript. The goal is to compare numbers and determine which one has the highest value.

The basic idea involves comparing numbers pairwise.

Explanation:

• The if statement checks if num1 is greater than num2.
• If true, num1 is returned as the largest.
• Otherwise (meaning num2 is greater than or equal to num1), num2 is returned.

There are a few ways to approach this:

This approach involves comparing numbers in a structured manner.

Explanation:

• The first if checks if num1 is the largest.
• The else if checks if num2 is the largest.
• If neither of the above conditions is met, num3 must be the largest (or equal to one of the others if they were tied for largest).

JavaScript provides the Math.max() function, which is the most concise and efficient way to find the maximum value among several numbers.

Explanation:

• JavaScript’s Math.max() function directly returns the largest of its arguments.

• Conditional Logic: Crucial for decision-making in programs.
• Comparison Operators: (>, <, >=, <=, ===, !==) are used to compare values.
• Logical Operators: (&& (AND), || (OR), ! (NOT)) can combine multiple conditions.
• Built-in Functions: Leverage language-specific features like Math.max() for cleaner and more efficient code.
