Return the Next Number from the Integer Passed

To return the next number from the integer passed in JavaScript, you can use the following approach:

Step 1: First, define a function that takes an argument `num`. This argument will be the integer from which you want to return the next number.

function nextNumber(num) {
  // code to return the next number
}

Step 2: Inside the function, use the following formula to return the next number:
nextNumber = num + 1

function nextNumber(num) {
  var nextNumber = num + 1;
  // return the result
}

Step 3: Finally, use the return statement to return the `nextNumber` variable.

function nextNumber(num) {
  var nextNumber = num + 1;
  return nextNumber;
}

Here is the complete code:

function nextNumber(num) {
  var nextNumber = num + 1;
  return nextNumber;
}

var result = nextNumber(2);
console.log(result); // Output: 3

You can also use the following shortened version of the function:

function nextNumber(num) {
  return num + 1;
}

var result = nextNumber(2);
console.log(result); // Output: 3
