Javascript Functions

Create a new function named max which accepts two numbers as arguments.

The function should return the larger of the two numbers HINT: will need a conditional statement to test 2 parameters to see which is larger.

So i have written

function max (num5, num12) {
 var answer =("num5, num12") 
if (5 < 12) { 
}
 return answer }

You can do this a few ways.

You can use an if else statement like so...

function highestNumber(a, b) {
  if (a > b) {
    return a
  } else {
    return b
  }
}

var result = highestNumber(100, 46); // will return 100

OR you could use javascripts Math.max method. This is a lot cleaner in my humble opinion....

function highestNumber(a, b) {
  return Math.max(a, b);
}

var result = highestNumber(40, 18); // will return 40

Hey Jimel,

You have a few mistakes in your code

  • You are setting the variable answer value to ("num5, num12").
  • You are comparing 5 < 12, it should be something like num5 < num12.
  • You are returning answer which has the value ("num5, num12") on it.
// Create a function that accepts 2 parameters
function max(num1, num2) {
// If num1 is greater than num2 it means that num1 is the largest of the two numbers, so we return num1.
   if (num1 > num2) {
      return num1;
// If num1 is not greater than num2 it means that num2 is the largest of the two, so we return num2.
   } else {
      return num2;
   }
}
// Now we call our function with the two numbers we want to compare.
max(5, 12);
